The Tomato-Chili Nexus: Reconstructing the Mesoamerican Influence on Europe through Taste and Method

By Serin Quinn

The earliest known recipe referencing tomatoes was published in Naples in 1692. This is not simply the earliest European recipe to include the ingredient, but the first written tomato recipe world-wide. The history of the tomato – a foodstuff indigenous to the Americas – is dominated by European sources: our recipes, botanical descriptions and illustrations all stem from either European or post-conquest authors.

How, then, can we use such European recipes to understand the cultural influence of Indigenous American cultures? This blog explores how following taste offers us a means to recreate the unrecorded past and to bring to the fore hidden histories.

I am not the first to note this issue: following Marcy Norton’s 2008 work Sacred Gifts, scholars have begun to reconsider the role of American foods in European cuisines. Nonetheless, studies to date have focused on foods that have distinct paraphernalia (chocolate cups or tobacco pipes) or that have necessary treatments, such as the nixtamalization of maize or de-toxification of cassava. The pre-Columbian history of the tomato is harder to grasp, but its study shows us that even the most ordinary of American foods had a fundamental influence on the food cultures of Europe.

[Xi]tomamolli: Mesoamerican tomato sauces

To reconstruct pre-Columbian tomato-usage (in Nahuatl xitomatl), we must consider the form and taste of food and relationship between ingredients.

The post-conquest primary sources we do have – ethnographies such as the so-called Florentine Codex and government reports such as the Relaciones Geográficas – provide us with two key pieces of information. These sources do not give us a fixed recipe of the type we would find in contemporaneous recipe European books, but there are notable consistencies in their reports that speak to common, repeated practice. Critically, these sources repeatedly tell us that tomatoes were consumed as a sauce or stew and that they were consistently paired with chili peppers: as the Relaciones report from Texcoco (1582) stated, ‘They have tomatoes and tomatillos, which serve as a spice with chilli, from which they make sauces and appetizers to eat’.

Ethnographic work suggests tomatoes and chilis were first charred to remove the skin and then pounded together using a stone molcaxitl (‘sauce bowl’) and a texolotl grinding stone. This sauce-paste was then used to flavour dishes such as tamales and stews of beans, turkey eggs or meat (deer/dog/turkey/fish/newt). As the authors of the Florentine Codex observed: ‘Where [it is] tasty, [it has] chili, salt, tomatoes, gourd seeds: shredded, crumbled, juiced’. This is the quintessential Mesoamerican tomato recipe, as recreated from common practice.

In the centuries following the conquest, tomatoes continued to be eaten in this way by the populations of New Spain. As one chronicler wrote in 1698, tomato-dishes were the ‘be-all, end-all of the stews of the Indies’.

Salsa de tomates: tomatoes in Iberia

Across the Atlantic, in the Spanish-controlled Mediterranean, we see a clear continuation of both these forms of cooking and of the tomato-chili nexus.

The earliest recipe, from Spanish Naples, is for a tomato sauce ‘in the Spanish style’, and sauces and stews/soups also form the bulk of recipes in Spanish and Portuguese. The author of a manuscript Portuguese cookbook (c. 1715) wrote: ‘Tomatoes in all foods, that is, in meat, in stews, or in roast sauces, add a particular flavor to everything’.

Almost all recipes from this period are directions to use tomatoes as a sauce or as the base for stews/casseroles (with one or two recipes directing tomatoes to be pickled or used in salads). If we deconstruct these recipes to their base elements, a consistent method appears that can be expressed as follows:

Take ripe tomatoes; roast them; remove their skins; mince or crush them until fine; mix with chili, oil and vinegar and [onions, garlic, ginger, cumin, oregano, or thyme], serve with [fish, chicken, eggs, beans, or rice].

Some aspects of the flavour profile varied between recipe in the choice of herbs, spices and alliums, but the addition of chili, as well as oil and vinegar, was almost always to be found. The association between the two foods was so strong that they were customarily depicted together in paintings.

Love apple sauce: tomatoes in Britain

The transfer of tomato-tastes to Spanish colonisers and subsequently to their homeland in Iberia is perhaps not surprising. Yet through tomato recipes we can see that the spread of Mesoamerican tomato-chili sauces travelled further, into the early modern British diet.

English recipes for tomatoes – then called love-apples – fall into two categories: pickles and sauces/soups. Recipes for these sauces use the methods seen above: rather than ‘roasted’ they are ‘baked’ and their skins removed by pulping through a sieve rather than peeling, but the result is the same. Importantly, alongside ‘Old World’ ingredients such as onion and ginger, almost all these recipes contained chilis. We see this across both print and manuscript recipes, and usually in the form of ‘capsicum’ or chili vinegar, as in the recipe below.

These sauces came to Britain not through direct colonial contact with Mesoamerica, as in Iberia. Rather, the authors of eighteenth-century encyclopaedias and gardening manuals attested to a different origin of influence: Jewish refugees, specifically Sephardi Jews fleeing the Spanish/Portuguese inquisitions of the 1720s. As one horticulturalist noted, ‘it is agreeable in Soups. Those who are us’d to eat with the Portuguese Jews know the Value of it’. As Iberian consumers once adopted a taste for the tomato from Mesoamericans, so they later brought it with them to their new home.

In both Iberia and Britain, therefore, we see how the tastes of a minority group can have a powerful and lasting impact on the diets and desires of the majority, and how knowledge is spread through a series of incorporations and re-introductions.

The enduring relationship between tomatoes and the chilis illuminates a path of cultural influence from pre-Columbian Mesoamerica to eighteenth-century Britain. While we lack detailed guides on how tomatoes were prepared prior to the conquest, understanding preparation methods and flavours profiles allows us to trace the movement of culinary knowledge over time and space and to reestablish the role of Indigenous American tastes in shaping European cuisine.

Rhyming Recipes in the Early Modern Arab Mediterranean

By Leonie Böttiger

On the purpose of the urjuza:

This urjuza I have entrusted / with useful benefits, all of them tested

Of what our collection will have need / so, accept what I say in evidence, indeed

O you who these matters investigate / memorise all that I relate

For I have set for humankind in my verse / nothing but the truth of all you observe[1]

Why versify a recipe, let alone an entire recipe collection?

Readers might be familiar with what is arguably the most famous of English rhymed recipes: the witches’ song from Shakespeare’s Macbeth, in which the three sorceresses cook up a potion featuring ingredients both disgusting and nonsensical. This Barbadian rum punch rhyme or Reverend Sydney Smith’s rhymed salad recipe might instead offer more delectable examples of culinary poetry, while The Recipes Project has previously highlighted playful aspects of recipes, including satire and rhyme.

Arabic, a language famed for its poetical tradition, also boasts its fair share of food-related poetry—but a curious North African craft recipe collection made up entirely of rhymed couplets might be a closer kin to the English playwright’s double trouble, though admittedly less renowned.

The Eloquent Poem in Rajaz[2] on the Proper Crafts was probably composed sometime in the fifteenth or sixteenth century CE by one Abu Bakr al-Kharrat, likely somewhere in North Africa, based on the manuscript evidence—we don’t have any other sources about his life. The Eloquent Poem has survived in at least five manuscripts which are now housed in Paris, Leiden, Gotha, and Djerba, and one of which is dated to 1579 CE. Arranged in four maqālāt (sg. maqāla) or treatises, the short book is a didactic poem which consists of recipes for various household and other craft activities.

Versified recipes can be considered an almost ‘double-didactic’ genre: both the recipe and the poem are inherently concerned with the transmission of knowledge. As such, they present an intriguing lens through which to approach the poetic adaptation and dissemination of knowledge: what does it mean to transform recipes for scribal arts and household activities into didactic verse?

For Abu Bakr, poetry had the decisive advantage of being easier to memorise and transmit—a device humans had taken advantage of for centuries, if not millennia, before its mechanisms were ever explained by psychologists and neurolinguists. He explains in his brief foreword:

“Now then, brother, […] I have compiled for you in this poem benefits and useful properties for whatever purposes you wish. You informed me that you are keen to attain it in a way that eases its memorisation and transmission, and I have abbreviated the composition and clarified what I have set forth of my knowledge…”

Abu Bakr does not mention any of his sources, but many of the recipes contained in the poem have parallels in older Arabic recipe collections from all across the Arabic-speaking world, dealing with stain removal and other crafts, as well as in books on the occult properties of substances, attesting to a fluid body of knowledge that was nevertheless transmitted somewhat cohesively.

Unlike his predecessors, Abu Bakr, however, did not seem to hold much esteem for established authorities: as we see in the excerpt above, as well as in several other places in his text, he continuously highlights his own expertise, claiming that he is presenting his own knowledge. Where older texts make frequent reference to Greek, Roman, or even Indian physicians and scholars (think Dioscorides, Galen, or Suśruta) to substantiate and verify the efficacy of their recipes, Abu Bakr does not mention any ancient authorities. This might reflect both a shift in how expertise was construed at the time the Eloquent Poem was composed as well as its expected audience: What use was it to namedrop Aristotle if his name meant nothing to your readers—or perhaps, listeners? It seems that Abu Bakr considered highlighting his own practice-based expertise a more useful strategy to convey authority onto his text.

So, what did that look like in practice? The following recipe, to remove stains from clothes, may give a little taste of Abu Bakr’s style (I have tried my best to retain the rhyme scheme):

Whoever loves knowledge, clearly to comprehend / Should vinegar and potash blend

In a pot, raised on the fire to stay / For three hours of the day

And wash the fabric and the wool with this / For it is described by my premise

I mean it removes every stain, alluded / before this, and is concluded.

About half of this recipe consists of material that is merely there to make the rhyme work. It thus facilitates memorisation but wouldn’t be strictly required to actually follow the procedure. Additionally, and similarly to its non-versified cousins, the recipe above does not offer any quantities or measurements apart from the “three hours” boiling time for the vinegar and potash. Now, stain removal is not necessarily an exact science, but the absence of such specifications indicates that people were likely familiar with the procedures described. This lack of measurements is also the case in recipes that require more precision, such as making inks, where a drop of liquid can mean the difference between a rich, saturated colour and a watery splotch:

Green verdigris, o you of bright mind / with vinegar smoothly grind

And mix it, my friend, with dissolved mastic / Write with it, it turns doubtlessly fantastic

Among the most amazing things with which to write / And ask, if you don’t know, someone who has tried!

As we have seen, Abu Bakr’s Eloquent Poem provides a unique glimpse into what was considered useful knowledge, addressing a wide array of needs in an easy-to-memorise format while stressing the importance of practical experience. Finally, italso offers practical solutions for getting rid of all kinds of pests—no quantities required, but PLEASE do not try at home:

Whoever wants to expel every mouse / from all the corners of the house

Should scatter arsenic on the fire / in his room or the house entire

He does this once, on a Friday / and doesn’t see a mouse in his house—all away!

Reconstructing an Italian Perfume from the Nineteenth Century

By Charlotte Gaudry

When we talk about historical reconstruction, “making” can be understood as the act of bringing the past back to life, recreating what once existed. This fits closely with the goals of the reconstruction I have in mind for my thesis project. It is not just about restoring objects or practices, but about exploring new ways of understanding and “making” history itself. It’s a process that can engage all our senses: sight, smell, touch, taste, and hearing. In this sense, reconstruction becomes a multisensory experience, one that opens up new possibilities through the intersection of experimental history and sensory studies. This approach feels particularly relevant for studying 19th-century Italian perfumery, a field that remains relatively under explored.

That’s why, as a PhD student in contemporary Italian history, I believe this research is not only necessary but also valuable in offering a new way of connecting with the past. Reconstruction, in this context, becomes a kind of immaterial materialisation, a way to make something intangible, like a smell, feel real again.

To give a bit of background: Italian perfumery in the 19th century evolved alongside industrialisation, which brought a wave of new knowledge and techniques. In the course of my research, I’ve found that information about perfumery is scattered across a variety of sources, from press articles and cosmetic manuals to texts on chemistry, pharmacy, floriculture, medicine, and hygiene. Yet, despite all this documentation, the one thing we lack is the scent itself. We’re left with only written descriptions and material traces to guide us. That’s what makes this work both incredibly challenging, deeply fascinating, but also very complex. 

Given the lack of material evidence for such ephemeral and intangible artefacts, we must seek clues through available sources. The most obvious sources are recipe manuals. These documents detail raw materials—whether natural, vegetable, animal, or synthetic—specifying their origins, processing methods, and the evolution of associated techniques, whether local or imported. They also describe mixing and boiling methods. The authors may integrate olfactory descriptions, providing a valuable sensory dimension that serves as an important reference in the reconstruction process. 

Recipe manuals have become some of my favourite sources. They give a real sense of the skills, techniques, and even the mindset of the time. They also reflect the impact of industrialisation, especially how chemistry and machinery started to change the way perfumes were made. What I find most fascinating about the 19th century is how it captures this turning point: traditional craftsmanship blending with new scientific and mechanical approaches.

These manuals don’t just list ingredients; they reveal which materials were in fashion, whether they came from Italy or were imported from abroad. Reading through different recipes helps me imagine the range of scented products people used—liquid perfumes, scented powders, pomades—and the role they played in daily life.

The illustrations are especially helpful. They make even the most complex machines or processes feel more understandable, almost like you’re being guided through them by someone who was there. They’re drawn with care, showing precise proportions and technical details that tell us a lot about how the machines worked. The accompanying text is often surprisingly clear too, explaining how each part functioned and how everything fit together. We missed some flowers or perfume bottles’ illustrations. Nevertheless, our large corpus overcomes that. 

Together, these manuals and illustrations give us a way to piece together, and potentially recreate, the technical world of 19th-century perfumery. For me, they’re like stepping stones that connect us directly with a forgotten craft. Nineteenth-century Italian perfumery thus emerges as an ideal laboratory for analysing the intricate dynamics of hybridisation between tradition and modernity. 

However, we may wonder if these documents are sufficient to understand how to recreate a specific recipe. Upon reading, we notice that some information is missing, primarily relating to tacit knowledge. 

This type of knowledge is often deeply rooted in personal experience, context, practice, and insights. Unlike explicit knowledge, which can be easily articulated and shared, tacit knowledge is intuitive and often subconscious. We must therefore use experimental history to address this issue. 

One of the major challenges I have run into while researching 19th-century Italian perfumery is language. Not just translating from Italian to French, but translating entire ways of thinking about ingredients, tools, and measurements that don’t always match up with our modern understanding. Some of the recipe manuals I am working with were written before Italy was even a unified country. So, naturally, there is no standardised system, especially when it comes to weights and measures. Some manuals use kilograms, but others rely on terms like oncia (ounce), dramma, or libbra (pound). Furthermore, the value of a libbra changed from one region to another. So the pound used in Tuscany was not the same as the one in Naples. That means a big part of my work has been setting up a kind of decoding system, figuring out what each unit meant in that specific place and time, so I can accurately interpret the recipes. But it also shows how important it is to approach these sources carefully. A tiny mistake in translation or conversion could completely change the formula, and with it, the scent of the reconstructed perfume. It is above all about translating an entire sensory culture. One that was shaped by chemistry, trade, and the slow but steady march of industrialisation. That makes every detail, from a single dramma to the function of a distillation machine, worth paying attention to.

To overcome these issues, we must use different sources and disciplines. The historian, relying on various sources like manuals, treatises, objects, preserved residues, etc. to reconstruct the recipe with the greatest possible precision. I’m not doing this alone. The real magic happens when I work alongside perfumers. They take all the information I gather and turn it into something tangible, real experiments in the lab, trying to recreate scents that haven’t been smelled in over a century. And then there’s the chemist, who steps in to help us make sense of how raw materials might have changed over time, or why certain reactions happen, or don’t. Even though we each speak our own “language” history, chemistry, and perfumery—we are all working toward the same goal: to bring a forgotten fragrance back to life. That collaboration is thus essential.

In the end, this kind of reconstruction isn’t just about copying the past. It is about bringing it to life in a way that people today can experience. That is what makes it so powerful. By recreating these forgotten scents, we’re not only sharing complex historical knowledge. We are making it real, tangible, and relatable.

It is a new way of doing history. One that doesn’t just rely on dates and documents, but on our senses, our curiosity, and a mix of disciplines working together. Whether it is through the nose of a perfume, the feel of an old recipe book, or the hum of a recreated 19th-century machine, we’re building bridges between then and now. And for me, that’s where the real interest of this work lies.


Charlotte Gaudry is currently a PhD candidate in History at the University of Grenoble Alpes, where she is conducting research under the auspices of the “Olfaction” Chair within the LAHRHA laboratory. Her doctoral thesis focuses on the history of Italian perfumery in the 19th century, exploring the intersection of olfactory heritage, industry, and cultural identity. Beyond her academic work, she has participated in various cultural and educational projects.

The Barclay Project

By Marissa Nicosia, with Christina Riehman-Murphy and Clara Drummond


Christian Barclay Jaffray (1680-1758) began gathering recipes for cookery, medicine, and dyeing cloth in 1697 when she was seventeen in a book that she titled “A Receipt Book, or, The Fruits of a Young Woman’s Spare Hours” (Manuscript, Scotland, 1697-1723).

This small, fine volume arrived at Penn State Libraries’ Eberly Family Special Collections as part of the “Robert Barclay of Ury family papers and maps” collection. Robert Barclay, Christian’s father, was a prominent Scottish Quaker leader and author of Apology for the True Christian Divinity (1678). The Ury family papers include Robert Barclay’s correspondence with William Penn and maps of his proprietary holdings in New Jersey and Pennsylvania as well as Christian’s receipt book. Although the collection was acquired primarily for the historical and geographical papers connecting the Barclays to William Penn and Pennsylvania history, the daughter’s recipe book is a true gem.

Read the transcription!

Penn State undergraduate students have transcribed the entire manuscript and published it through the library’s digital exhibition platform. Special Collections as well as the Preservation, Digitization, and Conservation team prioritized Christian’s receipt book for digitization and this foundational work facilitated a multi-year transcription project. During the 2021-2022 academic year, Penn State Abington students enrolled in the undergraduate research project “What’s in a Recipe?” undertook a complete first-pass transcription of the manuscript under the supervision of Heather Froehlich, Marissa Nicosia, and Christina Riehman-Murphy. In 2022-2023 Jonah Carver (PSU class of 2023) held a Bednar Internship and worked to edit and prepare the transcription for publication online by comparing the initial transcription created by Abington students with the digital images of the manuscript online and the original manuscript in the Special Collections library.

Bake Barclay!

With a little strategic updating to modify the original seventeenth-century instructions, Christian’s recipes are a delight in the kitchen. Since 2022, we have featured baking recipes from this manuscript in our annual, global, friendly competition between Penn State Libraries and Monash University Libraries: The Great Rare Books Bake Off. We especially recommend her delectable “Sugar Biskets.” Marissa has also updated a few more of Christian’s recipes as part of her ongoing Cooking in the Archives project.

Dye Wool in Sad Purple!

During the summer and fall of 2023, Jonah, Marissa, and Christina joined collaborators at the Center for Virtual Material Studies to recreate a few of Christian’s recipes for dyeing wool in gorgeous colors like the warm mauve “Maiden’s Blush.” While there are not yet published, modernized versions of Christian’s dye recipes, experienced practitioners can try their hands at her recipe for “Sad Purple” (aka dark or deep purple) using the published transcription. The dyed wool that we collectively prepared was displayed alongside the manuscript (and many other fascinating materials) in the Special Collections exhibit Sad Purple and Mauve: A History of Dye-Making (September 2023-January 2024).
