Anthropologists are interested in foodways, a term used to describe a society’s collection, production, and consumption of food. There is a particular interest in understanding how culinary traditions shape identity. It is not uncommon for archaeologists and cultural anthropologists to attempt to reconstruct food practices of the cultures they are studying, utilizing different types of clues. While written accounts, artwork, and visible food remnants help tell the story of a culture’s foodways, anthropologists also use residue studies of traces of food and drink in pottery, baskets, and gourds and stable isotope analysis of human bones and teeth, in which they measure isotopes (radioactive elements found naturally in food) to determine the diet of an individual and the environment in which they lived. These clues to ancient foodways can reveal a great deal about daily life. Archaeologist Lisa Duffy has studied ancient Maya cuisine using residue from pottery and grinding stones. Residues include many kinds of trace materials left behind on the artifacts, such as charred remains on the sides of a cooking pot or microscopic plant or animal remains on the surface of a vessel. So far, residues have been successfully recovered from seven ancient Maya sites across Guatemala and Belize, some dating from as early as 600 BCE. Some of the chemicals that have been identified indicate use of chili pepper, cacao, chocolate, and tobacco, among other herbs and spices. While chocolate compounds have been found on culinary artifacts from many different social strata, most other residues are specifically associated with certain social classes. Through studies such as this, foodways help scientists better understand the social differences and lifestyles of early cultures. Figure 14.4 The Maya used chocolate as an important ingredient in their diets and grew cacao as a domesticated crop. To make chocolate, seeds from cacao trees are fermented, dried, roasted, and ground into a paste. The grinding slab pictured here was traditionally used for the grinding stage in chocolate production.

In one experiment, physicist Seamus Blackley and his colleagues, archaeologist Serena Love and microbiologist Richard Bowman, developed a technique to extract hibernating yeast microbes left behind on porous Egyptian ceramics. These yeast microbes were dated to 4,500 years ago. The first step in their experiment was to sequence the yeast’s genome (i.e., map each of its genetic markers), through which they determined that it was not genetically the same as modern yeast and that it was as old as they had originally thought. The researchers then fed the yeast einkorn flour, made from a kind of wheat that would have existed at the time the yeast was originally active. As Blackley reported, “The yeast woke up right away.... It was kind of remarkable” (Blackley, Love, and Bowman 2019). The resulting bread was fine grained and well risen, with a pungent odor of brown sugar. Using experimental techniques such as these, archaeologists are able to tap into smells, tastes, and textures that were part of ancient foodways and may no longer exist in our cuisine today.
