One Hundred Delightful Tastes of Tofu: How Doable Was an Early Modern Japanese Recipe?

1 Comment

By Sora (Skye) Osuka

Tofu Hyakuchin (豆腐百珍, One Hundred Delightful Tastes of Tofu Recipes), originally published in 1782, is often considered the first cookbook that only focuses on one ingredient and the beginning of the Hyakuchin-mono (百珍物, One Hundred Recipes of Delightful Tastes) series. Harada Nobuo, Eric Rath, and other historians of Japan have argued that cookbooks published during the Edo period were tools for vicarious consumption of cuisines that the reader could not physically obtain. However, when we carefully analyze the contents of cookbooks written in the Edo period (1603-1868), we are surprised that they are filled with the practical knowledge, the latest cooking techniques, ingredients, and utensils of that time. It was also during the Edo period, in which society formed the basis of Japanese cuisine that is still visible in the present day. The role of cookbooks like the Tofu Hyakuchin, not only as symbols of townspeople (chonin, 町人) culture and the culture of play (Asobi, 遊び) but also as a form of collective knowledge of the people who supported culinary culture during this time, cannot be underestimated.

This piece challenges the generalizing discourse surrounding cookbooks during the Edo period by first examining the popularity and accessibility of tofu as food from primary sources aimed for everyday people. Then it analyzes key aspects of Tofu Hyankuchin that separate this text from other cookbooks during this time, such as utensils, specific cut sizes, and measurements of ingredients to highlight the components that could be seen as “practical knowledge” rather than “vicarious consumption.”

Many believe that tofu was not consumed among ordinary people in the first half of the Edo period. In 1500, Shichijyu-ichi ban Shokunin Utaawase (七十一番職人歌合, Matching Songs of Seventy-one Craftsmen) was published. Tofu seller (豆腐売り) is mentioned as the 37th job . In the accompanying illustration, a lady in a black kimono and white headband sits cross-legged on a low platform on a street selling large and small pieces of cut tofu. The author of the painting is believed to be Tosa Mitsunobu (1434-1525). A total of 71 sections and 142 craftsman figures are displayed. In addition to the traditional craftsmen involved in the construction of temples and shrines, more low-ranking people such as female craftsmen, saleswoman, entertainers, and prostitutes who are not directly involved in material or agricultural production, are also included. Through the Shichijyu-ichi ban Shokunin Utaawase, it can be assumed that tofu seller was one of the recognized occupations and tofu was available in the later Muromachi Period (1336-1573).

In the Kansei period (1789-1801) or the early 1800s, ranking tables (banzuke) became popular in Edo. Tofu cooking is mentioned in the Nichiyo Kenyaku Ryori Shikata Kakuryoku Banzuke (日用倹約料理仕方角力番付, Daily Frugal Cooking Method Competitive Ranking Table) which is in the same format as a sumo tournament flier. According to the table, there are two sides: Vegetable and Fish. The highest rank is Ozeki (大関). Under the Vegetable side, the Happai Tofu (八杯豆腐, Eight Cups Tofu) is ranked to Ozeki. Yaki Tofu (焼豆腐, Grilled Tofu) is ranked in the fourth rank of Sekiwake (関脇). Kinome Dengaku (木芽田楽, Baked Tofu with Sansho Tree-Sprout Miso Coating) is ranked in the fifth rank of Maegashira (前頭) in the spring section. Tofu related cuisines appeared a total of 15 times on the table.

Besides popular culture mentions of tofu, we can also see the prevalence of soy itself through Edo period edicts. Tokugawa Iemitsu issued the Keian Ofuregaki (慶安御触書, Keian Edict) in 1649 for the control of farmers. The edict consists of 32 articles, which warn of luxury life by peasants, such as alcohol, tobacco, and rice. The edict also demands people to devote themselves to agriculture. In the fourth edict, soybean planting is mentioned in the form of so-called aze-mame (畔豆, ridge beans), in which soybeans are planted in the ridges of rice paddy fields. It states that peasants must plant soybeans and azuki beans between their rice fields and farms. It is interesting to note the contemporary understanding of legumes’ ability to reincorporate nitrogen back into the soil. Although the people of Edo knew no such knowledge, legume planting may have helped farmers overall crop yield and efficient use of land. As the 4th edict decreed:

“Focus on cultivation, and planting to rice fields and vegetable fields, and at the same time, focus on production and prevent weeds from growing. If you take care of weeds and always cultivate the land with a hoe, you can get good crops and a lot of harvest. Then, plant soybeans and azuki beans on the bank in the fields to increase the crop as much as possible” (Keian Ofuregaki).

In the 11th edict, it stated that after experiencing famine, peasants must eat soybean leaves, which was also mentioned in the Ryori Monogatari [料理物語, Tale of Cooking], perhaps the most prominent early cookbook in Edo Japan. From the context of the 11th edict, the peasants had rice in the autumn, but in the later months, they had millet. The Tale of Cooking is written to support the peasant’s menu:

“The peasants are not thinking well, and they have no idea about the future. In the autumn, they feed rice to their wives and children without thinking about the harvested rice. Always in January, February, and March, they take care of rice and eat millet, wheat, Awa millet, Hie millet, vegetables, radishes, and make more millets, and do not eat a lot of rice. Immediately after experiencing a famine, do not waste time throwing away soybean leaves, azuki leaves, cowpea leaves, deciduous leaves of potatoes, etc.” (Tales of Cooking).

Around 1695, tofu was sold by vendors sitting by the road. We do not know for sure when tofu was first sold by walking street vendors, but after a big fire in Edo in 1698, sellers of dengaku (skewered grilled tofu with a sweet miso topping) started to appear.

In 1634, the Tale of Cooking was published. This was during the early part of Edo and is often considered the first Japanese cookbook written mostly in plain, syllabic Japanese. Although the author is unknown, the epilogue states that “This one volume of this cooking book does not require knife skills. This is for ordinary people and there are no cooking rules. This teaching is from our ancestors. Since I wrote the story of people to date, it is called the tale of cooking.” As for tofu related recipes, there are only two mentioned in the Ryori Monogatari in section 12 on boiled foods: Ise Tofu (伊勢豆腐) and Ryori Tofu (料理豆腐):

“Ise tofu: First grate yam. Cut the sea bream and grate it. Add one-third of grated yam. Add the egg white into tofu and grate it. Grate them well together. Spread a cloth on a cedar box and wrap it. Put it in hot water, press it, and then cut it. Spread cloth on the cedar box. Put it into boiled water, hold, and cut. Serve with arrowroot and soy sauce. It is also very good to sprinkle with chicken miso or wasabi miso. Also, it is good to serve only the tofu. I sincerely report the above recipe” (Tales of Cooking, 183).

If we take a closer look at the recipes, we see that there is little to no information about measurements, sizes, or utensils that are required to actually prepare these dishes.

A distinct feature of the Tofu Hyakuchin that shows that the book was not strictly for the purpose of play are the detailed cut sizes, measurements, and cooking utensils, potentially allowing readers to follow and recreate the dish. For instructions of cutting Tofu in the 72nd recipe, it instructs readers to “remove the coarse cloth texture from the surface of a whole tofu and cut off the four corners of the tofu, then cut the newly formed corners to make an octagon. Cut that into five or six smaller pieces. Season using sake, salt, and soy sauce” (Tofu Hyakuchin, 28). Another example is in the 96th recipe, readers are asked to “cut tofu in 2.4cm x 2.4cm x1.2-1.5cm cubes. On one skewer, place three pieces. Follow recipe number two (Kiji-yaki dengaku), grill until golden brown. Once it is grilled, remove them from the skewer. Place them in a Raku-ware teapot with a lid. Pour on hot pepper-vinegar-miso and sprinkle poppy seeds on top” (35).

Other detailed measurements are also explained in the 56th recipe, for example, “mix grilled tofu and Fukusa miso in a 7:3 ratio. Pound the mixture with a kitchen knife until it is one solid piece. Make into desired size, and lightly fry them. Season to desired choice”(24).  In the 81st recipe, furthermore, “use silken tofu. Boil six parts water to one-part sake. Once it is boiling add one-part soy sauce and let it reach a boil again. Place tofu into the mixture. The length of simmering is the same as number 92 of Yu-yakko. Remove the tofu right before it starts to float. Serve with grated daikon radish” (31). The recipes in Tofu Hyakuchin are in simple, syllabic writing and basic characters, with detailed measurements, and are easy for the reader to understand the method of cooking. In addition, it is easy to visualize the dish just by reading the instructions.

Introducing New Cooking Utensils

In one Tofu Hyakuchin recipe, it shows a new innovation: a charcoal stove specifically for making Kinome-Dengaku in the first tofu recipe. To proliferate varieties of cooking, it is essential to develop and invent new cooking tools. In the book, a new baking charcoal stove is introduced made of ceramic, which allowed for portability and better heat transfer than previous grills, as well as accessibility to a wider audience than traditional metal or steel grills. “Recently,” the book notes, “a new product was released for grilling miso dengaku (skewered tofu with miso sauce). About 60 cm in length; The width is about 8 cm; About 6 cm deep. This is made of pottery and has a hole in the bottom. There are many 1.8 cm holes (12).

There are also many cooking utensils made of metal introduced in the Tofu Haykuchin. We can assume that hardware stores were popular in the Edo period and selling metal products allowed more access for people to cook food at a higher temperature. For example, in the 40th recipe, a wire mesh (金の籠, Kane no amikago) is introduced:

“Simmer light-soy sauce with sake and salt. In a separate pan, bring a large amount of oil to a boil. Cut tofu into flat cubes and place them on a wire mesh. Fry the tofu by shaking it 2-3 times inside the oil. Once fried, immediately place the fried tofu in the pot of simmering soy sauce”(21). 

The 54th recipe also uses a sieve made of metal: “To make the mashed potato, boil mountain yam very well. Remove excess water and sift through a metal sieve (銅飾, Kanasuhinou)” (24). Moreover, in the 57th recipe, a metal spoon (金匕, Kanesaji) is used to “simmer whole tofu in a pot with no liquid over small heat. Remove the liquid that comes out of the tofu with a metal ladle”(25). 

The recipe book also mentions a specially shaped long wooden box (つきだし, tsukidashi) in the 100th tofu recipe, which has about the same cross section as that of a block of tofu, with a handle on one end, a screen over the opposite exit end, and a wooden pusher, which is used to push a block of tofu into the box and through the screen, thereby creating tofu noodles.

“To cut the tofu, use the tube used to make tokoroten [gelatin jelly strips]. Use silk string to make grids on the end of the tube. Point the tube directly into lukewarm water. Push the tofu through the tube to make a noodle-like shape. Let the tofu submerge in water as you push it through. Even when serving 100 people, it is important to cut the tofu immediately before serving”(37-38). 

Examining the contents of the Tofu Hyakuchin, this cookbook was not just a hobby of a cultured person, but all recipes are easy to make, delicious, and still seen today. It introduced detailed cut size and specific measurements of ingredients. It also introduced cooking methods such as frying, steaming, and boiling that could be easily done with the new invention of high-heat cooking utensils. From the other popular culture materials and Tokugawa edicts regarding the development of soybean production, we can see the possible accessibility of tofu. This paper is not to discredit previous scholars on this subject, whom I greatly respect, but to complicate our understanding and analysis of Edo period cookbooks.

Say Ohm: Japanese Electric Bread and the Joy of Panko

1 Comment

By Nathan Hopson

In 1998, the New York Times introduced readers to an exotic new ingredient described as “a light, airy variety [of breadcrumb] worlds away from the acrid, herb-flecked, additive-laden bread crumbs in the supermarket,” with a texture “more like crushed cornflakes or potato chips” than its plebeian brethren (Fabricant 1998). That ingredient was panko, which has since become a staple for American home and professional cooks alike. In 2007, panko accounted for only 3% of US breadcrumb sales, for instance. Five years later, one in six American households regularly stocked panko in the pantry. Panko caught on because it is crunchier (and stays crunchy under restaurant heat lamps), absorbs less oil, and adds more volume than traditional breadcrumbs (Nassauer 2013).

Why are these Japanese breadcrumbs different? How did they get to be that way? The story told by American manufacturers such as LA-based Upper Crust Enterprises―an ironic name given that the secret to panko is crust-free bread―is that “Japanese soldiers during World War II discovered [that] crustless bread made for better breadcrumbs as they cooked it with electricity from tank batteries, not wanting to draw the enemy’s attention with smoke from a fire”(Nassauer 2013). Upper Crust’s president, Gary Kawaguchi, affirmed this account in a recent interview.

This is a cool story. Turns out, the truth is just as cool.

Japanese inventors had tinkered with electric cooking prototypes since at least the 1920s. Then in 1933, the Imperial Japanese Army (IJA) commissioned a “field kitchen that can prepare both rice and bread”(Aoki 2019, 11). Cost was no object and time was of the essence. As Katarzyna Cwiertka has noted, the military generally advocated bread, but there was a special urgency in light of the logistical difficulties of supplying rice to new front lines in Siberia and Manchuria. In 1937, paymaster captain Akutsu Shōzō’s design became the “Type 97” field kitchen, first deployed with the IJA’s First Independent Mixed Brigade that year (Uchida 2020, 2–4). The 97’s cooker was an insulated wooden box with electrode plates attached to the base and four sides of the interior. The highly efficient cooking process Akutsu used goes by several names, including ohmic and Joule heating. It is a form of electroconductive heating that passes electric current through foods to heat them rapidly and uniformly, quickly producing a light, yeasty, crust-free bread.

After the war, companies such as Sony began selling rice cookers and bread machines that adapted these wartime technologies, and DIY home bread makers were showcased in magazines and newspapers. Influential women’s magazine Shufu no tomo and the inaugural issue of boys’ DIY magazine Shōnen kōsaku both featured instructions for bread makers derived from Akutsu’s design in 1946, reflecting the popularity of electric power in light of consumer fuel shortages and, conversely, excess generating capacity with military factories shut down (Uchida and Aoki 2019, 484).

In the 1960s, the new postwar frozen food industry hungered for high-quality breadcrumbs. Wheat had poured into Japan after 1945, the result of food aid; the use of bread and other wheat products in Japan’s school lunch program; and endless marketing promotions. Although ambitious American visions to recenter the national diet on wheat were soon abandoned, US agricultural imports and food technologies remained critical to Japan’s changing postwar food systems. Improved and upscaled food processing equipment met a market awash in cheap wheat, enthusiastic consumers (about half of whom owned electric refrigerators by the mid-1960s), and improved logistics. Frozen foods were among the shiny new things of postwar Japan’s shiny new “bright life,” and the mass use of frozen foods to cater the 1964 Olympiad and 1970 World’s Fair made them even more attractive symbols of Japan reborn.

These factors spurred rapid growth in breadcrumb demand, which was met in large part by the industrial-scale use of ohmic heating to create “electric breads” that were airy and uniform, and fried up crisply and uniformly when made into panko (Uchida and Aoki 2019, 485).

Tales from the Archives: Was There a Recipe for Korean Ginseng?

1 Comment

By Daniel Trambaiolo

As all of us continue to watch the COVID-19 vaccine rollout, and wait with cautious optimism for a time when we can heal and recover, I’d like to take a moment to revisit another medical breakthrough that required patience of its own. In this post from our archives, Daniel Trambaiolo recounts an exchange between a Korean and Japanese doctor as they “discussed” best practices for preserving and transporting the Korean wonder drug ginseng to Japan. I hope you enjoy our return to this tale of recipes, distribution logistics, and healing, no super-chilled storage freezers required.  -Joshua Schlachet

Ginseng_in_Korea

Ginseng, one of the best known drugs of the East Asian herbal tradition, can be purchased today almost anywhere in the world, but in the early modern period its availability was much more limited. The roots of Panax ginseng could be harvested only from its natural ecological range, in a region stretching across Manchuria, Siberia, and the Korean peninsula. In countries like Japan, where doctors relied on Chinese styles of herbal therapy but did not have direct access to herbal drugs that grew only on the continent, the roots had to be imported at high cost.

The cost of Korean ginseng became a source of concern in Japan during the final years of the seventeenth century, as the need to pay for the drug contributed to a steady outflow of Japanese silver that was used to pay for foreign products. During the early eighteenth century, the Japanese shogunal government encouraged doctors and herbalists to develop a domestic substitute, either by finding a native plant with similar medicinal properties or by discovering a way to cultivate Korean ginseng plants on Japanese soil.

Panax ginseng did not grow natively in Japan, but the related species Panax japonicus appeared similar and promised to have similar medicinal properties. However, the roots of the native Japanese species had a distinctive segmented appearance that led to Japanese doctors calling it “bamboo-segment ginseng”; their flavour was also more bitter and less sweet than the imported Korean product–a concern for many doctors, who believed that flavor was closely related to therapeutic efficacy. Some drug sellers claimed to possess secret methods that could transform the native herb into an equivalent of the imported drug, but how could these claims be evaluated?

Korean doctors were one obvious source of authoritative information on ginseng, but it was difficult to discuss the matter with them because the shogunal government had enacted strict policies limiting the movement of foreigners into Japan. Among the rare exceptions were the Koreans who travelled to Japan on diplomatic missions. Starting in 1682, these missions included a “medical expert” (K. yangǔi, J. ryōi 良醫) whose functions were to provide medical care for the members of the embassy and to allow Japanese doctors the benefit of Korean medical knowledge.

An early modern Korean embassy to Japan.

Neither the Japanese nor the Koreans could speak each others’ languages, so they communicated by writing down questions and answers in classical Chinese, a form of conversation known as “brush talks” (K. p’ildam, J. hitsudan 筆談). The records of these conversations were often preserved in manuscripts or books printed for wider dissemination, and they can offer us insights into the styles of cross-cultural communication that these embassies facilitated–as well as into the ways Korean and Japanese doctors tried to derive benefits from each other without giving away too much in return.

The following exchange on ginseng took place between the Japanese doctor Kawamura Harutsune and the Korean doctor Cho Hwalam during the Korean embassy of 1748. (The translation is based on the published version of their conversations, which was distributed by the prominent Edo bookseller Suwaraya Mohei.)

Kawamura: In our country there is a type of ginseng whose stem, leaves, flowers and berries are just as described in the Materia Medica; its roots are similar in shape to what Zhang [Zhicong] calls “bamboo-segment ginseng.” It is very bitter in flavor and unsuitable for use, so people customarily boil it with licorice root or process it with honey water. But although the bitter flavor departs and a sweet flavor emerges, it is not the original flavor.

However, my father found a processing method that is quite acceptable; it does not rely on the flavors of other drugs, but the bitter flavor departs and a sweet flavor emerges. When my father consumed [imported] ginseng, he would always see blood in his phlegm. When he consumed the ginseng that he had processed himself, he would also see blood in his phlegm. Looking at it this way, is its efficacy similar to the ginseng from your country?

Cho: While I was in Osaka, I already heard people talk about your country’s ginseng. Although when you see the stem and leaves it looks similar, after tasting its flavor and inspecting its form it is clearly not genuine. You can perform all sorts of marvelous transformations to alter its bitter flavor, but how could you use it? There is no method for processing ginseng: you should use it just as it is naturally. Don’t be confused about this!

Kawamura: Your explanation is sufficient to dispel doubts. However, among several pounds of ginseng from your country, some roots have a burnt yellow color and seem to have undergone processing. Moreover, during [the embassy of] 1711 the Korean doctor Ki Tumun transmitted a processing method to a disciple of my grandfather. However, the paper has been eaten by insects and is now difficult to read. I will briefly write it down here, but I beg you to enlighten me further.

[Thereupon, he told me the method for processing ginseng. It is marvelous, and I have submitted it to the authorities. I do not record it here, but I have recorded it elsewhere and keep it in my home.]

Unfortunately, there are no surviving records of what Cho transmitted to Kawamura, so it is impossible to know whether it was a genuine recipe used by Koreans for processing ginseng or merely one he invented on the spot to deflect Kawamura’s questioning. Kawamura may have decided to omit the recipe from the published version of the brush talks in order to profit by selling ginseng processed according to a “secret Korean recipe.” However, his opportunities for doing so would probably have been quite limited. A few years before the meeting between Cho and Kawamura took place, a different group of Japanese herbalists succeeded in cultivating Korean ginseng from seedlings smuggled into Japan from Korea. As this new source of cultivated ginseng became commercially viable, the demand for “processed” ginseng dwindled rapidly and the recipes for such processing were gradually forgotten.

Meals on Wheels: The “Kitchen Cars” and American Recipes for the Postwar Japanese Diet

Leave a comment

By Nathan Hopson

From 1956 to 1960, the USDA Foreign Agricultural Service (FAS) sponsored a fleet of food demonstration buses in Japan (“kitchen cars”) to improve national nutrition and fuel the nation’s economic recovery with more “modern” and “rational” cooking methods and, most importantly, ingredients (i.e. American agricultural surpluses: wheat, corn, soy, and to a lesser extent meat, dairy, etc.) The concept was first floated to the US by Dr. Ōiso Toshio, chief of the health ministry’s nutrition section, 1953-1963. Along with the school lunch program instituted under the US occupation, the kitchen cars became one of the most important tools for marketing American farm products in Japan. The school lunch program, centered on bread and (reconstituted skim) milk until the 1970s, taught young Japanese new tastes. The kitchen cars taught their mothers to reproduce those flavors at home.

The initial fleet of a dozen buses, operated by the Japan Nutrition Association (a semiprivate organ of the health ministry), reached over two million people in towns, villages, and apartment blocks across Japan. The nutritionists staffing the buses put their professional imprimatur on the many novel foods they demonstrated, and distributed samples, nutritional pamphlets, and the day’s recipes to their audiences of mostly housewives. The kitchen cars were wildly popular. When US funding expired, local Japanese governments built their own to meet public demand; the number exceeded 100 by the end of the 1960s. Though it is difficult (impossible?) to quantify, the kitchen cars contributed in subtle but profound ways to transforming the postwar Japanese diet.

Despite their popularity at the time, today the kitchen cars are mostly forgotten. When they are remembered, it is mostly for destroying “traditional” Japanese dietary patterns and contributing to the “Westernization” of the diet during the period of high economic growth. This backlash stems in part from the fact that American financing was hidden not just from the public, but also from all those who staffed or assisted with the kitchen cars. Still, in the short run, these buses were a win-win for the US and Japan. America’s Cold War “Food for Peace” campaign put agricultural surplus to work supporting a critical ally, and Japan received enormous amounts of free or cheap food and generous development loans.

The photo above shows a typical scene from a day in the life of the kitchen car. The audience crowds around the back of bus, which opens up like a thrust stage for the nutritionists to perform upon. The gathered women listen intently, some taking notes. The kitchen installed in the rear of the bus is the state-of-the-art chrome and gadgetry emblematic of the new postwar “bright life” of happy consumerism. The nutritionists in their white lab coats bring the authority of science. The foods they are preparing may not seem like the stuff of American farm surplus propaganda, but as Ōiso himself observed, “Propaganda is truly effective when people don’t notice it.”[1] To wit, the noodles are most likely soba: buckwheat mixed with (American) wheat. Even subtler is the use of sautéing, undoubtedly in (American) corn or soy oil. This kind of gradualist approach, expressed in slogans such as “Flour-based food once a day,” helps explain both why nobody suspected American involvement and why the kitchen cars were so popular and effective.

Few detailed records of 1950s’ kitchen car menus remain, but those that do are consistent with accounts from the 1960s. A list of favorites from mid-decade Okayama prefecture includes milk donuts, udon stew, sautéed amaranth leaves with liver, fried meat and vegetables with ketchup, vegetable cream soup, fried soybean fritters, chicken and peanuts in tomato sauce, bok choy with peanuts and mushrooms, and cheese sponge cake. Roughly simultaneously, the prefecture’s public health center sponsored competitions for original, tasty, nutritious, economical foods (about ¥20 each) using ingredients like soy, skim milk, and flour. Winners included vegetable omelets, fried tofu-wrapped sardines, fried sardine balls, and mysterious entries such as “nutritional bread” and “nutritional fried dumplings.”

These lists lend credence to the remarks of Richard Baum, Ōiso’s initial American collaborator. In a 1978 documentary, Baum expressed immense satisfaction at the kitchen cars’ success. As he explained, “the housewives would come out and gather around and learn how to make different wheat foods. And then they would get to sample the wheat foods. And they found these very delicious and so they would say ‘Oishii desu. Mō sukoshi’ [This is delicious. A little more, please].”[2]
