Recipes in the archives of the early Royal Society

By Sietske Fransen

‘What is a recipe?’ was the simple opening question asked by the organizers of the virtual conversation hosted by The Recipes Project. This month-long online discussion has made me look at the archives of the Royal Society with different eyes.

During my weekly visits to the Royal Society Archives in London I am usually searching for anything visual from the period 1660-1710. Once found, the particular page of archival material with something visual on it is added to the Making Visible database. With this database the Making Visible team is creating a research tool through which it will be possible to enter the archives on image level, and ask and answer questions about the usage of images in early modern science. Have a look at our blog in case you are curious to find out more, or follow us on twitter @MVCRASSH. However, while my colleagues and I are looking for images, we also come across many other interesting documents that are currently part of the early archives. Like recipes!

Those of you who have followed the Twitter storm during the #recipesconf might have seen that I have tweeted about recipes in the last few weeks: recipes for the making of pigments and varnish; food recipes (for bread, butter, and bacon); and medical recipes. The discussions on Twitter have made me come up with several questions. And even though there are too many questions to answer in one blog post, I will discuss them briefly, and hope to continue this wonderful conversation with so many colleagues around the globe.

First of all, why did all these recipes make their way into the archives of the Royal Society? When I started working on the Royal Society materials two years ago, I did not expect to find so many recipes for making food and drinks, nor was I expecting the Fellows’ interest in the making of pigments and varnishes. However, it turns out that the Fellows of the Royal Society were very interested in the history of trades, which made them collect recipes from artisans, including many recipes and treatises on things related the making of images, book printing, and engraving techniques.[1]

The food recipes might need to be seen from the perspective of making products in the house, with which men and women can show off their skills to their friends.[2] During my tweet-storm, I showed a set of recipes brought to the Royal Society by John Evelyn about how to make the best French bread. But also bacon, butter, cheese, and cider recipes are part of the collections in the archives.

In the case of the bread recipe we have the name of John Evelyn stuck to it. And it is indeed interesting to know who provided the Fellows of the Royal Society with the information now in the archives. Who were the sources for the recipes? Were they named? Relatively often we find a name on the recipe. Many to the recipes related to the art of picture making have male names on the recipes, such as Jonathan Goddard in the recipes for colours. Between the recipes I found several had a female name on them, such as the butter recipe from Mrs Elizabeth Papworth, and the recipe for a remedy for scurvy by Mrs Bancroft. Is this surprising? Not at all, since regular readers of this blog know very well that recipes were very often collected by women in early modern English households. However, from the perspective of the early history of the Royal Society it is definitely interesting how recipes from women are still part of the archives. Much more research needs to be done on the women around the Royal Society.

There was an interesting discussion about whether or not the description of a tool needed for the performance of the recipe (such as an oven for bread baking) should be treated as a recipe? Or is it even an ingredient? The description of the oven in John Evelyn’s bread recipe almost looked like a recipe inside a recipe, as it was so clearly describing the various things needed to make the oven and made sure it would actually work correctly. And a good working oven was a prerequisite for making the best bread in itself. Also here I am looking forward to a continuing discussion about tools in recipes!

Finally, I would like to quickly answer a question that Elaine Leong raised  about the many underlinings and crossing-out in a recipe for curing rabies. As I suspected the crossings were done in the original document that was brought in to the Royal Society. The recipe was thought important enough to make it into the Royal Society’s Register Book, where we find it again in volume 7. All the crossed out sections that you can see in the image to the left are omitted from the neat version of the recipe in the Register book. Also the information about the effective cure of the His Majesties’ dogs is left out. But instead we do find a short Note Bene, explaining that the plant named in the recipe as “Starr of the Earth” has several Latin and vernacular namens “known among Botanists”, which will make it easier to find this ingredient.

Thanks to the organisers of the #recipesconf for giving me a great excuse to look into recipes in the Royal Society Archives and for all the stimulating conversations online!

Seasonality and the (Re)creation of Early Modern Color Worlds

By Jenny Boulboullé

Color played an important role in the early modern world across a number of areas from arts and crafts to Christian religion to politics to natural history and philosophy. In recent years, scholars have begun to explore how early modern men and women engaged, produced and conceptualized colors within and across color worlds.[1] Just as in early modern culinary and medical recipes, seasonality is a recurrent theme in artisanal recipes. The art of preservation was highly valued for its powers to make flavors and healing properties of foodstuffs, plants and herbs endure well beyond their seasonal availability. In my contribution to the seasonality series I focus on recipes that celebrate the art of color preservation and on the mindful attention to seasons called for in color making recipes. I am particularly interested in the challenges that recipes for making natural dyes and pigments from seasonal products posed to modern historians trying to reconstruct them.

Today the symbolic significance of colors in early modern Europe is perhaps most readily associated with the compellingly colorful medieval and renaissance art works that have survived in sacred spaces and museums.

But in the pre-modern period a deep concern with colors was not limited to the arts: colors were associated with the four humors and close attentiveness to colors was of vital importance to practices of healing in the Hippocritean and Galenic medical tradition.[2] The perception and display of colors was also highly charged with political meanings: colors were a form of symbolic communication and played an important role in consolidating and displaying religious and secular power relations. European courts and courtly events were important sites of “chromatic politics” as contemporary witness accounts and meticulous historical reconstructions of ephemeral, yet splendid and compellingly colorful festive events have shown.[3]

The historical reconstruction of a sixteenth-century dress, originally created for the Augsburg Imperial Diet from 1530, is a particularly compelling example of the politicized use of brightly colored dress made from dyed textiles.[4] The owner of this dress and his contemporaries might have regarded its colors “as related to intrinsic qualities and powers”. Deep scarlet reds were regarded at that time “as carriers of life and heat, while a strong yellow was linked to gold as metal, which had given its powers by the influence of the sun”. Ulinka Rublack notes the challenges encountered during the reconstruction process. The yellow color obtained in their first dying trials “was just not quite vibrant enough” which was detrimental “as faded hues of yellow could have negative associations of weakness and coldness”.[5]

Other sixteenth century recipes for ‘yellows’ from organic sources, demonstrate that making natural dyes of this color depended on local seasonal knowledge. As Marieke Hendriksen has discussed, here in Utrecht, we are building a new database of artisanal recipes. A quick search in the Artechne Database yields several fifteenth- and sixteenth century German recipes for green and yellow colors that call for buckthorn berries (some with precise indication for picking times, like this one for “Green color” from 1543). Here an Italian one from the anonymous Padua Manuscript (ca. end 16th/17th century), translated and published in English:

To make giallo santo

Take the berries of buckthorn towards the end of the month of August, boil them with pure water, until the water is loaded and thick with color; add a little burnt roche alum and then strain it. You may boil the strained liquor to make the color deeper, mixing with it some very pure gilder’s gesso; then make the color into pellets, and dry them in the shade.[6]

In color recipes such as this one, seasonality and intimate knowledge of seasonal products sensitivities to additives play a key role. Berries had to be picked at specific times of the year to attain the right hues, and while the juice of ripe buckthorn, available in most of Europe, gives a greenish color, also known as sap green, one needs to get hold of unripe berries, fresh or dried, in particular a species imported from the Middle East, also known as “Persian berries”, to attain the deep golden yellow hue that the reconstruction team had envisioned for this dazzling sixteenth-century dress.[7] Only by patiently repeating the dye processes using the right berries picked at the right moment, can the desired vibrant hue of rich quality be achieved – both in the early modern period and during 21th century reconstruction.[8]

Thus, the commission of brightly dyed dresses for display at important events must have been a time-consuming affair that required planning long ahead of the political event and entailed a collaborative process of sourcing and experimenting that depended not only on seasonal knowledge and availability, but was also prone to risks of seasonal change. As Rublack’s work shows, reconstruction research makes us of acutely aware of the complexities and risks posed to those who aspired a part in the “chromatic politics” of the Holy Roman Empire in the sixteenth century. Moreover, as I will show in my next post, color recipe reconstructions allow us to experience the efforts and knowledge that went into the creation of early modern color worlds, which have become unfamiliar to our modern period eye.

‘Thus it prevails against its time’: distillation and cycles of nature in early modern pharmacy

By Tillmann Taape

In past centuries, devoid of freezers and heated greenhouses, the seasons affected medicines as well as foodstuffs. In addition to pickled vegetables and stored grain, early modern people worried about their provisions of healing plants and animal substances. These, too, had their season: many herbs were considered most powerful when picked in May, and ‘May dew’ collected from fragrant meadows at this time of year was said to have many healing properties. In his Destillierbücher (distillation manuals), published in the early sixteenth century, the Strasbourg surgeon-apothecary Hieronymus Brunschwig addresses the challenges which arise in pharmacy from nature’s cyclical changes. He explains that most preparations of fresh medicinal herbs are ‘unkeepable’. For example, ‘if you pound herbs, roots or other substances and squeeze the juice from it, then it becomes unpleasant, does not last, […] and soon putrid corruption ensues’.[1] Even with dried materia medica and compound drugs, their medicinal virtues faded over time.

Brunschwig knew this all too well from personal experience. As an apothecary running his own shop near the fish market, maintaining a stock of efficacious remedies was his chief responsibility and expertise. The issue of pharmaceutical provisioning was taken very seriously by Strasbourg’s magistrates. Twice a year, they would send round a committee of medical experts to all apothecary shops, to ensure that no perished goods were stocked, and to throw away any that had gone off.

Brunschwig’s understanding of the material world was shaped by his experience as a pharmacist and shopkeeper, but also by the cosmology and medical theory of his day. While the heavenly spheres were characterised by material perfection and changelessness, all matter on earth was made up of the four elements (air, water,fire, earth) and subject to their constant permutations. They were doomed to endless cycles of generation, change, and decay. Material stability was only possible where the elements were in perfect balance, ‘as you can see in May when it is neither too dry nor too humid, neither too warm nor too cold’.[2]

Brunschwig’s seasonal simile is revealing: a perfect balance of elements is just as rare and fleeting as those precious few balmy weeks in May. As well as pointing to the instability of all earthly matter, the language of seasons and their cold, hot, dry or moist qualities was associated with early modern ideas about the stages of human life. Youth, health, reproduction, decline and death were analogous with the annual cycle of flourishing and decay in nature – a relationship which is richly illustrated in a set of anonymous seventeenth-century engravings (see here for an interactive digital reproduction). The idea of changing seasons was emblematic of an early modern view of the material world which was characterised by instability. Human bodies fluctuated with the shifting balance of their humours, and the very substances which could be used to cure the resulting ailments were themselves fleeting and, in Brunschwig’s words, ‘unkeepable’.

Faced with such difficulties, Brunschwig and others turned to a branch of knowledge with a longstanding commitment to imitating and manipulating natural processes underlying the transformations of matter: alchemy. In particular, Brunschwig describes distillation as a powerful artisanal technique to ‘keep the unkeepable’.[3] Distillation was the art of separation, and in the case of medicinal simples, Brunschwig claimed, their ‘soul’ or healing virtue could be separated from their ‘body’, that is to say the material dross made up of the problematic four elements. Thus liberated, the healing ‘spirit’ of a plant in the form of a distilled water could be bottled and neatly stored on Brunschwig’s alphabetically ordered shelf, where they would keep well beyond their harvest season, for up to three years. Later Destillierbücher echo the idea that one can ‘keep these waters over the year’ as a major selling point of distilled remedies.[4]

While distillation in theory had the power to produce pure and incorruptible ‘quintessences’, this was far too laborious for everyday pharmaceutical practice. Brunschwig wrote for an audience of ‘common men’ as well as artisan colleagues, and most of the distilled remedies he discusses are much more pedestrian. They still have some of the elemental qualities of the original herb, and are ultimately perishable. Compared to ‘unkeepable’ plant juice, however, their decay is slower and more predictable. Brunschwig confidently charts the decline and change in a water’s healing powers over the years, and even gives instructions for ‘recharging’ them. A water can be saved by infusing it with fresh herbs and distilling it once more – thus, Brunschwig reassures his readers, a distilled remedy can ‘prevail against its time’ for another year.[5]

In the early modern world of matter, the seasons symbolised cycles of change and decay which spelled trouble for healers and makers of medicines. In some of the earliest vernacular works on pharmacy, Brunschwig describes distillation as a powerful tool for defying the material corruption of seasonal changes.

Constance Hall’s ‘Carrott Pudding:’ A Rendition

The following post is by an undergraduate student, Jessie Foreman, who worked with me on a research placement this summer, as part of the Undergraduate Research Opportunity Programme at the University of Essex. She spent part of her time transcribing early modern recipe books for the Early Modern Recipes Online Collective, along the way discovering interesting old recipes and even trying her hand at them. What I appreciate most about her following post is the way in which she highlights the assumed knowledge behind cooking, now as well as then.

A carrot pudding, how hard could it be?

Being a total beginner to early modern recipes, it was only logical that I should find a very simple recipe–not necessarily all that easy to do… I finally found a recipe that wasn’t cut off at the sides, used sixteen eggs and could feed the whole street… or require any ingredients that I couldn’t get from the local Co-op. In fact, I thought I was one step ahead of the recipe, since I had a fan-assisted oven and an actual Early Modern Assistant (thanks Nan!). How naïve I was!

As instructed in the recipe, we started by boiling three large carrots in a saucepan to fulfil the order of ‘4 spoonfulls of Carrotts.’ My Nan did start to scrape them before they were boiled, noting that it would be easier to do while they were still raw and not boiling hot, but we stuck to the recipe and scraped them after they were boiled. Beating the carrots in a mortar also proved to be very ineffective when it came to taking the pudding out of the oven, as you could see that they hadn’t distributed very well. I’m not trying to give baking advice to Constance Hall, but maybe she should think of grating in a few more things for a more even flavour.

Next were the eggs. I should’ve known that with ten eggs (two of which had the yolks removed) and a pint of cream, that I’d have needed something else substantial so it doesn’t come out as a runny mess. We whisked them up, but only to a normal whisked egg consistency – ‘beat them well’ leaves a lot to the imagination.

After that we added a generous amount of Aldi’s Own Brandy (in place of sac)k and softened butter, along with cream, salt and nutmeg. We used a spring whisk in lieu of not being able to use an electric mixer, and came out with a butter lump mix and cramp in one hand. It was hard to get rid of the lumps of butter in the mix, which had started clumping together and kept getting harder to remove. With the help of a spoon we did manage to squish all of them, but I wonder if the smaller remaining lumps can be blamed for the wobble on top of the pudding when it was in the oven. At ten minute intervals while the pudding was in the oven, I had to drain a growing lake of butter from the top of the pudding.

Grating the breadcrumbs was a nightmare: I’d bought fresh bread that morning, so it was very fresh and doughy. We should’ve used day-old bread, but by the time my Nan flagged that up, the carrots were already boiling, and the batter, already made. The recipe did not specify how much bread we should put in, only just enough to make it into a batter. As the mix was already sort of looking like a batter, we added in enough so that the grated bread was distributed evenly and went all the way through.

This was one of the main challenges we encountered while trying to follow this recipe: in any recipes, both old and new, there is a substantial amount of implied knowledge in the recipes. Given that fewer people would have read Hall’s manuscript recipe than modern printed recipe collections, there is even more implied knowledge; her audience was much more selective to begin with.

This wasn’t to last, though, as when we were pouring it into the baking tin, all of the mashed carrot and bread immediately sunk to the bottom. It was at this point that I started to think that the pudding might not quite turn out as planned… but there was nothing to do about it now, so I put it in the preheated oven for half an hour, draining Lake Butter every ten minutes. When the timer started beeping, I stuck in a knife to see if it was baked through. The knife was covered in grease, so we turned up the oven a little and left it again for ten minutes.

By the time the timer rang again, the top of the pudding was very brown, so there was no way that it could last any longer in the oven without getting burned. Whatever was inside of the tin now – whether cooked or sludge – was the finished product. I left it on the side to cool for about twenty minutes before turning it out onto a plate. The good: it solidified and kept its shape! The bad: just as predicted, everything had sunk to the bottom, so there was a very uneven distribution.

The pudding had mixed reactions from the official taste testers. My Mum said that the top of it, where there were no breadcrumbs, tasted like an egg custard. She quite enjoyed it. My Dad? He spat his into the bin.

Trying out this recipe wasn’t exactly a resounding success, but I thoroughly enjoyed a somewhat blind cooking experience and it felt like I was doing Constance Hall’s version of the technical challenge on The Great British Bake Off. If you’re not sure what this is, you should definitely check it out, where you’ll see baking disasters even worse than mine!
