Cipriano Piccolpasso’s Recipe for the Transmutation of Matter

By Steve Wharton

Cipriano Piccolpasso, Tav. 20, illustrations associated with the making of ‘lustres’, I Tre Libri Dell’Arte Del Vasajo… (1556-75), Dallo Stabilimento Tipografico, 1857.

Certain recipes can tell us a great deal about the cultural and sometimes the technological contexts within which they were compiled and disseminated. In his mid-sixteenth century Italian treatise, the Three Books of the Art of the Potter.., Cipriano Piccolpasso (1523-79) discussed and illustrated the technology and the manufacturing processes that were central to the making of tin-glazed earthenware pottery.[1] Frequently described as having been produced between the years 1556 and 1558, though revised throughout his lifetime, and as an instruction manual, the manuscript was unpublished until the mid-nineteenth century.[2] Today, it is considered the authentic voice of the sixteenth-century Italian potter. However, as I have discussed elsewhere, Piccolpasso’s descriptions are based on observation of the techniques and processes employed by the potters of Castel Durante, rather than practice. Nevertheless his treatise is consistently and frequently cited in highly technical physical and chemical analyses of Renaissance glaze and related technology.[3] The recipes discussed include those for colour as well as those for ‘ruby’ and ‘gold’ lustres: that is the addition of pristine metallic surfaces to otherwise finished ware. Piccolpasso says of them: ‘…I do not intend to go on further until I have discoursed to you upon gold maiolica, from what I have heard of it from others, not that I have ever made it or even seen it being done. I do know that it is painted over finished wares…’

While Piccolpasso is passing on hearsay, he nevertheless includes a recipe for what he calls Rosso da Maiolica [red maiolica]:

A            B

Red earth                           oz           3             6

Armenian Bole                 oz           1             0

Ferretto of Spain             oz           2             3

Cinnabar                            oz           0             3

to which he adds: ‘…with this last mixture ‘B’, include a calcined silver carlino [a burnt coin]’. In his marginal notes he confirms that ‘…this last mixture “B” is called golden maiolica’.

The inclusion of particularly cinnabar is at first a mystery; it has no function in a recipe such as this. It is only when we know that cinnabar is a compound of mercury and sulphur and that all the ingredients are ground together in a pot of red [i.e. strong] vinegar, one of the ‘sharp waters’ employed by alchemists, that things begin to make a little more sense. During the period, what were described as the ‘arts of fire’, which included the making of pottery, were also used to make not only high status bronze-cast sculpture and gold-cast jewellery, for example, but also to manufacture and prepare more ubiquitous substances such as pigments and other colouring agents for an array of manufacturing techniques. These included easel and fresco painting, tesserae for mosaics, fabric dyes and the decoration of glass and indeed pottery. As has been observed, alchemy, in terms of practical chemistry, was primarily concerned with the making of industrial products by using chemical processes; it was not necessarily concerned with the occult, the mystical or the spiritual.[4]

What Piccolpasso described was and is still known as a ‘transmutation lustre’ [my emphasis] in which a paste based upon raw clay is applied to the surface of a pot. It is a well-known technique: the fifteenth-century Hispano-Moresque potters used a red ochre clay corresponding exactly to that included in this recipe. A silver salt was added, in the form of a calcined carlino, together with a copper compound, known as Ferretto of Spain, to produce ‘gold’ lustre. No gold was ever used and in that sense it is the perception of gold that becomes significant.

The transmutation of base material into gold, however, was central to one of the alchemists’ most important aims, and mercury, sulphur and ‘sharp water’ were all part of the process. In his discussion of this recipe, Piccolpasso may well have been relying on what he knew of the presence of alchemy in all kinds of chemical and physical practice, including the production of gold maiolica. More specifically, he raises the question: to what extent might the potters of north-central Italy, in employing their own art of fire, be considered alchemists? What is more certain is that the philosophy associated with alchemy provides an insight into the ways in which knowledge and what kinds of knowledge were gathered and transmitted during the period. Ultimately, Piccolpasso’s record of what he understood as the recipe for ‘gold’ lustre reflected the endeavours of contemporary scholars and indeed pottery practitioners to cope with the challenges of defining and connecting all the different kinds and parts of knowledge that were circulating at that time.

English Gingerbread Old and New

By Stephen Schmidt

Food writers who rummage in other people’s recipe boxes, as I am wont to do, know that many modern American families happily carry on making certain favorite dishes decades after these dishes have dropped out of fashion, indeed from memory. It appears that the same was true of a privileged eighteenth-century English family whose recipe book now resides at the New York Academy of Medicine (hereafter NYAM), under the unprepossessing label “Recipe book England 18th century. In two unidentified hands.” The manuscript’s culinary section (it also has a medical section) was copied in two contiguous chunks by two different scribes, the second of whom picked up numbering the recipes where the first left off and then added an index to all 170 recipes in both sections.

The recipes in both chunks are mostly of the early eighteenth century—they are similar to those of E. Smith’s The Compleat Housewife, 1727—but a number of recipes in the first chunk, particularly for items once part of the repertory of “banquetting stuffe,” are much older.  My guess is that this clutch of recipes was, previous to this copying, a separate manuscript that had itself been successively copied and updated over a span of several generations, during the course of which most of the original recipes had been replaced by more modern ones but a few old family favorites dating back to the mid-seventeenth century had been retained. Among these older recipes, the most surprising is the bread crumb gingerbread. A boiled paste of bread crumbs, honey or sugar, ale or wine, and an enormous quantity of spice (one full cup in this recipe, and much more in many others) that was made up as “printed” cakes and then dried, this gingerbread appears in no other post-1700 English manuscript or print cookbook that I have seen.

And yet the recipe in the NYAM manuscript seems not to have been idly or inadvertently copied, for its language, orthography, and certain compositional details (particularly the brandy) have been updated to the Georgian era:

25 To Make Ginger bread

Take a pound & quarter of bread, a pound of sugar, one ounce of red Sanders, one ounce of Cinamon three quarters of an ounce of ginger half an ounce of mace & cloves, half an ounce of nutmegs, then put your Sugar & spices into a Skillet with half a pint of Brandy & half a pint of ale, sett it over a gentle fire till your Sugar be melted, Let it have a boyl then put in half of your bread Stirre it well in the  Skellet & Let it boyle also, have the other half of your bread in a Stone panchon, then pour your Stuffe to it & work it to a past make it up in prints or as you please.

From the fourteenth century into the mid-seventeenth century, bread crumb gingerbread was England’s standard gingerbread (for the record, there was also a more rarefied type) and, by all evidence, a great favorite among those who could afford it—a fortifier for Sir Thopas in The Canterbury Tales, one of the dainties of nobility listed in The Description of England, 1587 (Harrison, 129), and according to Sir Hugh Platt, in Delightes for Ladies, 1609, a confection “used at the Court, and in all gentlemens houses at festival times.” Then, around the time of the Restoration, this ancient confection apparently dropped out of fashion. In The Accomplisht Cook, 1663, his awe-inspiring 500-page compendium of upper-class Restoration cookery, Robert May does not find space for a single recipe.

The reason for its waning is not difficult to deduce. Bread crumb gingerbread was part of a large group of English sweetened, spiced confections that were originally used more as medicines than as foods. Indeed, the earliest gingerbread recipes appear in medical, not culinary, manuscripts (Hieatt, 31), and culinary historian Karen Hess proposes that gingerbread derives from an ancient electuary commonly known as gingibrati, whence came the name (Hess, 342-3). In England, these early nutriceuticals, as we might call them today, gradually became slotted as foods first through their adoption for the void, a little ceremony of stomach-settling sweets and wines staged after meals in great medieval households, and then, beginning in the early sixteenth century, through their use at banquets, meals of sweets enjoyed by the English privileged both after feasts and as stand-alone entertainments.

Through the early seventeenth century banquets, like the void, continued to carry a therapeutic subtext (or pretext) and comprised mostly foods that were extremely sweet or both sweet and spicy: fruit preserves, marmalades, and stiff jellies; candied caraway, anise, and coriander seeds; various spice-flecked dry biscuits from Italy; marzipan; and sweetened, spiced wafers and the syrupy spiced wine called hippocras. In this company, bread crumb gingerbread, with its pungent (if not caustic) spicing, was a comfortable fit. But as the seventeenth century progressed, the banquet increasingly incorporated custards, creams, fresh cheeses, fruit tarts, and buttery little cakes, and these foods, in tandem with the enduringly popular fruit confections, came to define the English taste in sweets, whether for banquets or for two new dawning sweets occasions, desserts and evening parties. The aggressive spice deliverers fell by the wayside, including, inevitably, England’s ancestral bread crumb gingerbread.

As the old gingerbread waned, a new one took its place and assumed its name, first in recipe manuscripts of the last quarter of the seventeenth century, and then in printed cookbooks of the early eighteenth century. This new arrival was the spiced honey cake, which had been made throughout Europe for centuries. It is sometimes suggested that the spiced honey cake came to England with Royalists returning from exile in France after the Restoration, which seems plausible given the high popularity of French pain d’épice at that time—though less convincing when one considers that a common English name for this cake, before it became firmly known as gingerbread, was “pepper cake,” which suggests a Northern European provenance. Whatever the case, Anglo-America almost immediately replaced the expensive honey in this cake with cheap molasses (or treacle, as the English said by the late 1600s), and this new gingerbread, in myriad forms, became the most widely made cake in Anglo-America over the next two centuries and still remains a favorite today, especially at Christmas.

By the time the NYAM manuscript was copied, perhaps sometime between 1710 and 1730, molasses gingerbread was already ragingly popular in both England and America, and evidently the family who kept this manuscript ate it too, for the second clutch of culinary recipes includes a recipe for it, under the exact same title as the first. Remembering the old adage that the holidays preserve what the everyday loses, I will hazard a guess that the old gingerbread was made at Christmas, the new for everyday family use.

150 To Make Ginger Bread

Take a Pound of Treacle, two ounces of Carrawayseeds, an ounce of Ginger, half a Pound of Sugar half a Pound of Butter melted, & a Pound of Flower. if you please you may put some Lemon pill cut small, mix altogether & make it into little Cakes so bake it. may put in a little Brandy for a Pepper Cake

An interesting question is why the seventeenth-century English considered the European spiced honey cake sufficiently analogous to their ancestral bread crumb gingerbread to merit its name. It may have been simply the compositional similarity, the primary constituents of both cakes being honey (at least traditionally) and spices. Or it may have been that both cakes were associated with Christmas and other “festival times.” Or it may have been that both cakes were often printed with human figures and other designs using wooden or ceramic molds. Or it may possibly have been that both gingerbreads had medicinal uses as stomach-settlers. In both England and America, itinerant sellers of the new baked gingerbread often stationed themselves at wharves and docks and hawked their cakes as a preventive to sea-sickness. (Ship-wrecked off Long Island in 1727, Benjamin Franklin bought gingerbread “of an old woman to eat on the water,” he tells us in The Autobiography.) One thinks at first that the ginger and other spices were the “active ingredients” in this remedy, and certainly this is what nineteenth-century American cookbook authors believed when they recommended gingerbread for such use. But early on the remedy may also have been activated by the treacle. Based on the perhaps slender evidence of a single recipe in E. Smith, Karen Hess proposes that the first English bakers of the new gingerbread may have understood treacle to mean London treacle (Hess, 201), the English version of the ancient sovereign remedy theriac, a common form of which English apothecaries apparently formulated with molasses rather than expensive honey. I have long wondered what, if anything, this has to do with the English adoption of the word “treacle” for molasses (OED). Perhaps a medical historian can tell us.

Coffee: A Remedy Against the Plague

By Lisa Smith

1721, London: The plague raging in Marseilles threatened London’s busy ports. The British government took action, asking a core group of physicians to devise a plan in case the plague reached London. Smallpox was already rampant and the King had ordered a series of inoculation experiments on prisoners. Troubled times.

Enter the impecunious botanist Richard Bradley. (I discussed his interesting life in a recent blog post.) When he wasn’t in debt to booksellers, he made a living from popular medical and scientific writings, such as The virtue and use of coffee, with regard to the plague, and other infectious distempers (London, 1721). He wrote: “At this time, when every Nation in Europe is under the melancholy Apprehension of an approaching Plague or Pestilence, I think it the Business of every Man to contribute, to the utmost of his Capacity, such Observations, as may tend to the Service of the Publick.”

And in the face of the plague and smallpox he offered… coffee. Remedies prescribed by other physicians, he insisted, “are little different from each other.” Coffee, however, “is of excellent Use in the time of Pestilence, and contributes greatly to prevent the spreading of Infection.” Who knew?

Apparently the Turks. Bradley explained: “in some Parts of Turkey, where the Plague is almost constant, it is seldom mortal in those Families, who are rich enough to enjoy the free Use of Coffee.” In his treatise, he discussed coffee’s efficacy and provided (most tantalizingly for the coffee-mad Brits) “an Account of the best Method of roasting the Berries, and preserving them after roasting.”

I present to you Bradley’s instructions for preparing coffee. First, he recommended spreading out the ripe berries to dry and harden beneath the sun. The husks were then to be removed so that the berries could be toasted in an “airy place to clean them.” Finally, the berries were ready for the roaster, and this was an important step: the roasting process, Bradley claimed, would determine “the Goodness of the Liquor.” Never fear, though, Bradley had “taken some pains to experience the best Method of roasting it.” His conclusion was that the berries would be heated most equally by placing them in an iron vessel and turned on a spit over a clear or charcoal fire. His personal preference was “roasted in a middle way, not overburnt.” To modern readers, this seems like a lot of work, but Bradley reassured his readers that this process could easily be done at home, as apparently many “Persons of Distinction in Holland” did.

Making the beverage also required special equipment and techniques. To prepare the decoction, earthen or stone vessels were best, as metal spoiled the flavour. Boiling the coffee evaporated “too much of the fine Spirits”. Pouring boiling water over the powder of ground berries and infusing it for four or five minutes in front of the fire would be better and “much exceeds the common way of preparing it.” He provided an alternative, too: grinding the berries into powder, adding the powder and water into a stone or silver coffee pot and leaving the pot in front of the fire for a couple minutes. The liquid was always “thick and troubled” after brewing, but could be made “clear enough for drinking” by adding a spoonful or two of cold water to force the grounds to sink.

Coffee was worth the effort, being the ultimate cure-all. Bradley described its many virtues, which included treating head pains, vertigo, lethargy, coughs, moist and cold constitutions, consumptions, swooning fits, digestive problems, sleepiness, running humours, sores, scrofula, drunkenness, rheumatism, gout, intermitting fevers and infection. It could also purify the blood, provoke urination, stimulate the menses and deworm children. Indeed, it was particularly beneficial for menstruating women. According to Bradley, Arabian women drank coffee during their “periodical Visits, and find a good Effect”, such as contraction of the bowels and toned up genitals. Coffee was not for everyone though. Those suffering from melancholy vapours, hot brains, or paralysis should avoid it.

The reason that coffee would be so efficacious in treating infectious disease was that it lifted the spirits—and those “whose Spirits are the most overcome by Fear, are the most subject to receive Infections”. The correct use of coffee supported the drinker’s “vital Flame”, protecting the drinker from fear and despair. To gain coffee’s maximum benefits, Bradley recommended the following dosage: at least twice a day, first in the morning and at four in the afternoon.

Coffee breaks: good for your health!

Recipe Organization: It’s not as easy as A, B, C.

By Elaine Leong

In my last post, I bemoaned the lack of a flexible search engine and information management technologies in the ‘favourites’ recipe box of the Epicurious iPhone app.  While still declaring my adoration for the app, I would like to talk a little more about issues of categorization in alphabetical information organization.

Now some of you might wonder, is she seriously offering a post about information categorization and alphabetization? Well, yes I am! And I bet this will even spark debate around your dinner table tonight!

Why don’t I start by sharing with you some of the recipes in the ‘B’ section of my Epicurious app recipe box: Baked pork chops with a parmesan sage crust, Baltimore crab cakes, Barbecue turkey burgers, Bass with herbed rice, Beef stroganoff and Blueberry buttermilk pancakes.

Of course, this is a historical recipes blog and so why don’t we pair this with a look a few of the recipes under ‘B’ in Johanna St John’s alphabetically organized mid-seventeenth century recipe book: for a kanker in a woman’s Brest, Dr Mathias for the whites and the weaknes in the Back, for a Bone ach excellent,[1] for Bleeding at the nose, For a Blast or the poison of the Toad,[2] for any knob or hardnes in the Brest or milk quard,[3] For the Bitting of a mad dog never failing and Mr Boyles Balsame of Sulphire.[4]

As you can see, inadvertently, the electronic search engines of the Epicurious iPhone app used several different knowledge categories to create the list of my favourite recipes beginning with ‘B’.  Here we have cooking method (baked, barbecue), locality (Baltimore) and ingredient (bass, beef and blueberry).  Johanna St. John, too, uses several different categories: parts of the body (breast, back, bone), action (bleeding), type of medicament (balsame), and external actions on the body (blast, dog bites).

Alphabetization and categorization is not as simple as A, B, C. While it is obvious that the Epicurious app merely assumed that the first word of each recipe title represented the key word, Johanna St. John’s parameters for categorization are not so clearly laid out. In fact, it appears that she herself was unsure about particular groupings and, in a later reading of the books, re-categorized a number of recipes.  Take a look at this folio, from the ‘W’ section, below:

Wellcome Western MS 4338, fols. 210v-211r.

 Many of the recipes on this page are to be used during childbirth. Some ease the experience of the mother-to-be, while others address potential complications.  In my mind, these recipes were first collected in the ‘W’ section as St. John saw them as a cohesive body of knowledge dealing with Women’s health concerns. However, if you look closely, you can also see a number of letters written to the right of the recipe titles.  Thus, a ‘D’ is written next to ‘To hasten delivery’, a ‘R’ next to ‘For an immoderate flux of the Redds’ and a ‘G’ next to ‘A Glister to be given in labor’ and so on…

Initially, these letters baffled me but after a bit of pondering, I realized that they are records of St. John’s second attempt to categorize her book of medical knowledge. Evidently, the second time round, she decided that a remedy to haste Delivery should be filed under ‘D’ rather than ‘W’, and that the ‘Redds’ and ‘Glister’ are the keywords in the other two recipes. St. John’s first pass at categorization suggests that, for her at least, there is a defined body of knowledge dealing with women’s health issues. In her second pass, this knowledge was folded into the rest of her collection.

So, where recipes are concerned at least, our methods of categorization are revealing of how we imagine and view bodies of knowledge. They also, as we now know, play a crucial role on whether we can ever find the required recipe again.  After all, I don’t immediately look under ‘B’ for pork chops or crab cakes, do you?
