The amalgamated Holidays officially kick in this week, so it’s time to think about festive things to eat and drink. Last year at this time, I seemed preoccupied with the latter, but now I’m thinking about food. I came across my grandmother’s recipe for molasses cookies–very thin, crispy and buttery, my absolute favorite, and started wondering about the principal ingredient. There must have been tons of it here in Salem in the nineteenth century, as it was the key ingredient in rum production and there were so many distilleries here. I know that molasses was imported into New England from the West Indies in the colonial era, but it think there were domestic refineries in the nineteenth century: was it produced in Salem? If so, where? Molasses-making is a messy business: was Salem ever in danger of experiencing its own version of the disastrous 1919 Great Molasses Flood in Boston? And what about consumption (besides rum): molasses does seem to have been much more in demand a century or so ago than now: why? There are so many recipes out there–for Black Jacks, still produced by America’s oldest candy shop, Ye Olde Pepper Candy Companie right here in Salem, as well as for another local molasses creation, Anadama bread, not to mention Indian Pudding, Boston baked beans and Boston brown bread. Molasses seems to be as characteristically New England  or “Boston” as the Red Sox. Then the English historian in me kicked in and I confronted the age-old question:  what’s the difference between molasses and treacle? Then the sixteenth-century historian in me kicked in, and I wondered what was the connection between molasses and the root of that old English word treacle, theriac, which was sold as a powerful panacea across early modern Europe. And just like that, my mind had wandered/wondered from cookies and candy to plague cures.

The migration of medieval medical recipes into the culinary sphere was not always a straightforward process, but it’s best to proceed from the past rather than the other way around. Theriac was an ancient electuary (medicinal paste) used first and foremost as an antidote to venomous snake bites. In the classic case of fighting fire with fire, The flesh of the snakes themselves was an essential ingredient, along with lots of others–64 in all in the classic Galenic recipe. In the course of the Renaissance, theriac was compounded to various formulas and came to be regarded as a universal antidote and panacea, with that produced in Venice generally regarded as the most effective, and the most expensive, naturally. As poison was associated with plague in the late medieval medical mentality, so theriac became the key plague antidote and consequently its preparation was serious business: under official supervision to ensure the proper process and correct composition.

Despite its (undeserved) reputation for efficacy, Venetian theriac could not crowd out the market in plague cures and regional recipes began to develop. In England, there were several major developments in the use and perception of theriac over the sixteenth and seventeenth centuries: in typical English fashion, the foreign word had long been anglicized as “treacle”, and  “Venetian Treacle” became an ingredient in variant plague cures and preservatives, rather than the exclusive antidote at about the same time that the London College of Pharmacists ruled that treacle need not contain snakes, and treacle (sans Venetian) started appearing in both medicinal and culinary recipes. Everything really changed–or came together–in the course of the seventeenth century, an era that was characterized by many, many recipes for “treacle water” as well as increasing imports of refined sugar from the West Indies, along with its by-products. These sweeter syrups, collectively called treacle, began to replace honey in the medicinal “London Treacle”, at about the same time that they started to appear as key ingredients in recipes for gingerbread, tarts, and puddings. So treacle comes to mean any syrup made during the sugar-refining process: black treacle, golden syrup, blackstrap, and molasses–all of which were relatively cheap ways to sweeten your plague water or your pudding. There were also treacle “lozenges” that soothed the throat and provided a bit of “sweatmeat” at the same time, and a recipe for gingerbread cakes that closely resembles that for my grandmother’s molasses cookies.
