As humans, we want to control heat. We want to create heat, temper or even extinguish it, depending on context and purpose. We have a very limited temperature range at which we are comfortable (some microbes and bacteria can survive temperatures as low as -20C and as high as 130C), so we spend an incredible amount of time managing heat, whether it is our body temperature or that of our homes, offices, laboratories, cars, or food.
When we started planning this series of blog posts in early May, we could not have suspected how appropriate the theme would feel by now. While much of northwestern Europe has not seen rain in weeks and is sighing under a heatwave with temperatures rising to 37C/98F, we have fled to airconditioned spaces to edit the posts. Climate-wise, heat is seasonal in these regions, but it has always played an important role in recipes year-round, all around the world, from antiquity to the present day, in fields as diverse as alchemy, chemistry, art, cooking, medicine, and personal grooming.
The common denominators of heat in all these realms are that it is either internal – emanating from the human body – or external, naturally occurring from the sun, thunder, or lava, or man-made through friction or fire. In the posts in this series, we will see a wide variety of attempts to control these different kinds of heat through recipes and instructions.
Some of our authors recreate such attempts by reconstructing experiments outlined in historical art technical and chemical sources. Indra Kneepkens recounts how she discovered through reconstruction research that sometimes for a recipe to make sense, it should not only be followed to the letter, but also be read between the lines. Ruben Verwaal and Marieke Hendriksen use their experiments with two reconstructions of small chemical ovens to reflect on the role of experimental heat in the development of theories on the nature of life in the eighteenth century. Working in a similar vein but with culinary recipes, Marissa Nicosia, from Cooking the Archive, examines the problem of heat control in her recipe recreation adventures, outlining the challenges of translating cooking instructions meant for the early modern hearth to the modern gas stove.
Other authors in the series took our invitation as an opportunity to investigate heat in medical theories across time and place. Aileen Das kicks off this series by arguing that heat occupied a central place in ancient Greek, Roman and medieval Islamicate theories about the human body and its care. Taking on the smelly problem of perspiration and body odor, Cari Casteel reminds us that this issue is as old as mankind and offers several remedies from Roman authors. Catherine Rider, on the other hand, examines notions of heat in fertility remedies in medieval England, noting that, whilst popular, heat-based treatments (to either increase or reduce heat in the body) were not the only kind of fertility aid available to English couples. The series concludes with two posts focused on fever and disease. Writing on in Late Imperial China, Marta Hanson introduces us to ideas of fever in Chinese medicine. Finally, Nukhet Varlik turns our attention to the ambiguities inherent in early modern taxonomies of infection diseases, exploring fever as a symptom and as a disease category.
We’ve had a great time editing this series – hope you enjoy reading the posts wherever you are. Happy summer and stay cool!

P.s. We were so inspired by our contributors’ posts that we’ve decided to dedicate the December issue to (you guessed it) COLD!. If you’re interested in joining the conversation, send a short pitch to email@example.com.
In 2017, The Recipes Project celebrated its fifth birthday. We now have nearly 650 posts in our archives and over 160 pages for readers to sift through. That’s a lot of material! (And thank you so much to our contributors for sharing such a wealth of knowledge on recipes.) But with so much material on the site, it’s easy for earlier pieces to be forgotten. So, the editors have decided that, every now and then, we’ll pull something out of the archives to share with our readers anew.
This month’s we re-feature a post by Colleen Kennedy, first published in August 2013. I think that it fits very well with our conversations this month, don’t you?
The violet (Viola odorata) is cited in several herbals and many recipe books as a particularly sweet scented, fragrant flower. Herbals, such as Culpeper’s, describe the violet as a “cold and moist” plant, with many medicinal qualities. It is used as a laxative, and as a treatment of syphilis and uterine complaints; it counterbalances choleric humors, is good for many lung ailments, eases headaches and sleeplessness, and is a general panacea.
Violets are also commonly used in recipes, either as “cakes of violet,” “candied violets,” “conserve of violets,” or “syrup of violets,” as flavoring for metheglins (meads), and to add aromatic qualities to vinegars and other recipes:
To Make Syrup of Flowers:
Take of Violet flowers fresh and pickt, a pound, clear water boiling one quart, shut them up close together in a new glazed pot a whole day, then press them hard out, and in two pound of the Liquor, dissolve four pound and three ounces of white Sugar, take away the scum, and so make it into a Syrup without boiling. (Woolley 6)
Any of Hannah Woolley’s recipe books are a good place to begin to study early modern recipes utilizing violet flowers. Violet’s pleasant odor is also the source of its medicinal powers and cause for its common domestic usage.
So, what does the violet smell like? English, alas, lacks a smell-vocabulary, and violet is repeatedly only listed as “sweet” or “fragrant.” Avery Gilbert considers the two distinct “voices” available to modern perfume makers: “Ingredient Voice” (the actual list of and proportions of ingredients) and “Imagery Voice” (“atmospherics, the drama of seduction, passion, and mystery”) (15). It is in that latter voice that we move closer to the more detailed early modern accounts of the aroma of violet.
For example, modern perfume blogger Normand Cardella, in his review of Yves Saint Laurent’s Paris, muses on the smell of violet: “So… what does a violet note smell like? Well… it’s powdery, a little sweet and decidedly sad. Musically, a violet note in perfume would be a minor chord.”
Likewise, for early modern writers, the violet is also a sad and musical aroma. Francis Bacon, in his essay “Of Gardens” (1625), links pleasurable odors and sounds (and much earlier than our modern perfumers): “And because the breath of flowers is far sweeter in the air (where it comes and goes like the warbling of music) than in the hand, therefore nothing is more fit for that delight than to know what be the flowers and plants that do best perfume the air”. Violet is his favorite perfumed flower: “that which above all others yields the sweetest smell in the air is the violet”.
The violet’s “imagery voice” is most fully articulated in Duke Orsino’s opening lines of Twelfth Night:
“If music be the food of love, play on.
Give me excess of it that, surfeiting
The appetite may sicken and so die.
That strain again, it had a dying fall.
O, it came so o’er my ear like the sweet sound
That breathes upon a bank of violets,
Stealing and giving odour. Enough, no more.
‘Tis not so sweet as it was before.” (1.1.1-8)
Much of the language here that applies to music or love is equally applicable to the sensation of smelling violets, especially violet’s unique chemical compound and its effect on the sense of smell. As Diane Ackerman describes: “Violets contain ionine, which short-circuits our sense of smell. The flower continues to exude its fragrance, but we lose the ability to smell it. Wait a minute or two, and its smell will blare again. Then it will fade again, and so on.”
The discovery of its isomer ketones did not occur until the late nineteenth century, yet, its affects were all very real experiences for early modern writers, such as Shakespeare, who attempt to distil and capture the essence of violet in distinctly beautiful terms, with the violet “stealing and giving odours.”
The “dying fall” of Orsino’s sad tune is like the melancholy aspects of the violet, evoking impermanence, transience, and death. Even Orsino’s command to stop the music can also describe the anesthetic properties of ionine. As Orsino complains though, the scent, the song, the sensations, and so on is “not so sweet as it was before.”
Orsino’s very mind, in its melancholic state, is affected by sweet airs—whether sad songs or fragrant violets. As the early modern brain was believed to be acutely affected by odors, and the violet emits a particularly sweet and sad aroma, the botanist and herbalist John Gerard’s regard for the violet’s olfactive and affective properties should not be surprising:
[Violets] haue a great prerogative aboue others, not onely because the minde conceiveth a certaine pleasure and recreation by smelling and handling of those most odoriferous flours, but also for that very many by these Violets receive ornament and comely grace …And the recreation of the minde which is taken hereby, cannot be but very good and honest: for they admonish and stir up a man to that which is comely and honest… do bring to a liberall and gentle manly minde, the remembrance of honestie, comelinesse, and all kindes of vertues. (Chapter 312: “Of Violets” 849-850)
Gerard nicely summarizes the memorable, virtuous, affective, symbolic, and olfactive properties of the violet that we have been sniffing out in this brief essay.

We do not have many recipes from the ancient world and certainly none presented in the user-friendly format found in today’s cookbooks with precise measurements, cooking times and images of the finished product. Some ancient recipes are found at the end of agrarian handbooks, like those produced by Cato the Elder (234-149 BC) (for more see Catherine Draycott’s post https://recipes.hypotheses.org/5005), while others are described as part of a philosophical dinner party (Athenaeus’ Deipnosophistae). The most famous recipe book, and the one which most reconstructed Roman recipes are based, is Apicius’ De re coquinaria or On the subject of cooking. Compiled sometime during the 4th century AD and named after an infamous 1st century AD cook, it contains recipes for vegetables, pulses, meat, seafood and game. Ingredients are listed in the text along with rough instructions for the preparation and cooking of the dish (think instructions for the technical challenge in The Great British Bake Off). The lack of ingredient quantities suggests that it functioned as part coffee table book and part chef’s manual, whereby the cook already had a good understanding of ingredient combinations and quantities. In other words, it was not for the beginner home cook.
Despite a lack of precision and clarity in these surviving recipes, it is possible to gain a detailed understanding of the sensory experience involved in the preparation and consumption of these dishes. This is due to the survival of several pieces of Roman kitchen equipment and at times, the food remains themselves. At sites like Pompeii and Herculaneum (Italy), which were destroyed by the eruption of Vesuvius in AD79, we not only have cooking pots, plates and serving dishes, but also the remains of the kitchens and dining rooms where the food was prepared and eaten.
So what was it like to make and eat Roman food? Let’s look at one of Apicius’ recipes in detail.
Lentils with mussels: take a clean pan, (put the lentils in and cook them). Put in a mortar pepper, cumin, coriander seed, mint, rue, pennyroyal, and pound them. Pour on vinegar, add honey, liquamen, and defrutum, flavour with vinegar. Empty the mortar into the pan. Pound cooked mussels, put them in and bring to heat; when it is simmering well, thicken. Pour green oil over it in the serving dish.
[Apicius, On the subject of cooking, 5.2.1, from Grocock and Grainger 2006: 209]
The first thing you may notice about this dish is the vast number of flavours and seasonings involved. In addition to the various herbs, the recipe also calls for liquamen, a fermented fish sauce similar to the Thai fish sauce Nam Pla, and defrutum, concentrated grape syrup made from boiled down grape juice. Roman dishes are notorious for their seemingly strange and startling mix of flavours. However, before we get to the taste, let’s start with sensory experience of preparing this dish.
Firstly, let’s assume that this dish is being prepared for a dinner party in a wealthy Roman household. If you were the one making the food you would have been a slave, working in a hot, small, smoky kitchen. Roman kitchens are readily identifiable by their large ceramic hearths. Cooking took place on the hearth; the space beneath is just for the storage of fuel, usually charcoal or wood. The lack of chimneys in Roman kitchens means that there was poor ventilation and the smell of the cooking food would have been quite strong. The small size of most kitchens, even in larger houses, meant that the room would have been hot, even in the winter.
At least two pieces of cooking equipment are required to make this recipe, a pan and a mortar. The mortar would have been a mortarium (image), a large shallow ceramic bowl with stone inclusions in the bottom to provide a rough grating surface. All the seasonings would have been ground by hand using a mortarium and wooden pestle. The pan (perhaps made of bronze) would have been placed on a metal or ceramic tripod with charcoal underneath. The varying materials of the mortarium, pestle and pan would have made the tactile experience quite dynamic. Once the dish was finished, depending upon the wealth of your owners, you would have poured the finished product onto a ceramic, bronze or silver platter. You’d then promptly move on to preparing another dish as Roman dinners usually consisted of several courses.
Now let’s shift gears and say you’re a guest at the dinner party and you have the opportunity to taste and smell this dish. The combination of flavours in this recipe, and particularly the mixture of the liquamen,defrutum, honey and vinegar would have given it a sweet and salty taste. In my experience, having made several Roman dishes, the flavour combination is strange but not jarring or unpleasant. Roman food tasted much more like modern Thai or Chinese cuisine than modern Italian with its frequent combination of sweet, sour, and salty. The black pepper in the dish, imported from India, would have provided a hint of wealth and exoticism as it was by far one of the most expensive and foreign seasonings you could use at this time. If you had grown up consuming a Roman diet then this dish would have smelled and tasted very normal to you. The herbs, in addition to appearing in numerous other Apician recipes, are also frequently mentioned by other ancient authors, suggesting that they formed an important part of the Roman diet. This importance is confirmed by the recovery of many of the herbs, and in particular coriander, at sites throughout the Roman Empire.
The military and merchants carried and imported these herbs to all the corners of the Empire, perhaps to evoke a taste of home. Some individuals native to the northern provinces, such as Gaul and Britain, adopted these seasonings into their local cuisines. In addition to probably enjoying the taste, they used them to display their wealth or allegiance to Rome.
In sum, there is much sensory information that can be gleaned from Roman recipes and the archaeological remains of food preparation and consumption. What is perhaps most striking is the vastly different interactions and experiences of those in the kitchen compared to those in the dining room!

Who was Gershom Bulkeley? (you may well ask). A Harvard-educated Puritan gentleman from an important New England family, Bulkeley spent most of his life in Connecticut as a colonial divine, physician, and magistrate of upstanding (and by contemporary accounts obstinate) character. Bulkeley was also an iatrochymist – an aspect of his work that is only now starting to receive scholarly attention – and prolific compiler of notes about the medico-alchemical experiments that he conducted in his laboratory, likely a part of his dwelling place.
About 25 miles from where Bulkeley once lived, there now exists a kind of biblio-bunker in the University of Connecticut Health Center. This is where the Hartford Medical Historical Society Library keeps its collection of rare books and manuscripts. And this is where twenty-four manuscripts that are either by or associated with Bulkeley ended up. NB: there is treasure buried in this underground archive! (I am sure that as a Puritan with millenarian expectations, Gershom himself would be comforted to know that in the event of some kind of apocalyptic event, his notebooks will survive intact.)
I came across this cache back in 2011 while chasing down different leads for my dissertation about one of Bulkeley’s contemporaries, another Harvard-trained Puritan minister-physician-alchemist named John Allin (1623-1683). But in going through the various manuscripts, I was drawn to one of Bulkeley’s notebooks in particular: Bulkeley MS 5.
This is a small book that has been rebound using the cover from a 19th-century book of fairy tales, and it contains a series of entries about alchemical experiments that Bulkeley undertook between 1703 and 1706 scrawled across eight pages, with an additional sixty-three pages oriented upside down at the back of the book of more extensive laboratory notes of ongoing experiments, dated 1702 to 1707. At some point in time, both sets of notes were bound together with Bulkeley’s (undated) abridged copy of the Institutiones medicae by Lazare Rivière (1589-1655) – i.e., two hundred and forty-four densely written pages of Latin in a neat and minute hand – sandwiched between the aforementioned two sets of laboratory records. Intriguing stuff…
…because Bulkeley crammed this notebook full of particulars about chymical substances, instrumentation, and techniques. Bulkeley worked with different chymical substances for pharmaceutical production. His recorded experiments are filled with actions (tasting, weighing, drying, stirring, observing, waiting), and his laboratory entries document a range of output (he made salts, spirits, powders, pills, oils, dissolvents, elixirs). In their preparations, Bulkeley worked with iron, copper, and antimonial substances, as well as mercury, arsenic, silver, coral, and turpentine, and he used various chymical processes (calcination, coagulation, sublimation, evaporation, distillation). Bulkeley also detailed the equipment he used, describing things like various retorts (one is silver) and curcurbits (a glass one, a silver one), heavy and light scales, a blue jug, a copper vessel, an alembic, a receiver.
Another striking feature of this notebook is Bulkeley’s use of naked senses – taste, touch, and sight – as tools of investigation in his experiments. Bulkeley describes the consistency of experimental matter in comparison to common foodstuffs (“pudding” features large in his notes as a standard for assessing viscosity). Bulkeley also records the presence, or absence, of “lixiviate”, “vinegar”, “alcalisate”, or “urinous” tastes; interestingly, these references to tasting generally occur (when they do) at the conclusion of a given entry. Bulkeley’s haptic perception in the lab comes across in three entries, which record experiments that took place between January 27 and February 1, 1702. Here, Bulkeley detailed a distillation process involving nitre, mineral iron, and oil of vitriol (the objective appeared to be the production of aqua fortis), whereby an outcome of these distillation experiments was to harvest the caput mortuum.
Bulkeley observed that the dregs from January 27th “looked pretty white,” while that from January 29th was reddish, and he concluded with the comment, “Both the Cap. mort came out easily enough & crumbly but the 2d was not so soft & easy as the first/”. This seems to indicate mixed results in Bulkeley’s estimation. A third (and likely final) entry dated February 1 indicates the continuation of this experiment, with some changes in ingredients (i.e., the addition of flowers of sulphur) and procedure (Bulkeley undertook the sublimation of the matter in question). Notably, Bulkeley recorded that he did not lute his receiver (meaning that he did not undertake the preventative measure of smearing a claylike compound around this vessel to seal and thusly protect it in heating procedures).
This time, things did not go so well with the experiment:
I could not get no more off the broken pot: & flowers in the head that I could save, [6…] : that is in all. But it was the same pitcher in which I had destilled A. F. put in before, suc. Janr 27. & 29. & now it was cracked & had leaked a little out into the sand, had drunke up some into it; & I could not get the Cap. mort cleane off, nor the flowers absolutely cleane: & tis very Pbable some might evaporate, the Rec. not being luted on./ The sulphur in the Capt Mort was not fixt, but which upon a coale readily smoake & flame burne with a very fine blew flame./
These entries about the caput mortuum show Bulkeley’s bodily way of knowing as a form of assay, a testing procedure that links sensory analysis with chemical analysis in his evaluation of the progress of his work. This also shows that Bulkeley paid just as much attention to detailed sensory descriptions of his failures in the lab as he did to successes.
Bulkeley MS 5 is a valuable artifact of Bulkeley’s heuristic laboratory methods in the production of chemical pharmaceuticals, likely destined for use in his medical practice. While this notebook presents us with puzzles (what prompted its compilation? how was it used?), at the same time we are granted open access into Bulkeley’s experimental activities, a window into his dynamic medico-alchemical operations in a colonial community at the turn of the 18th century.
