There are several definitions of cuisine. I like Warren Belasco's best:

"Drawing largely on anthropological sources, I define cuisine as a set of
socially situated food behaviors with these components: a limited number of
"edible" foods (selectivity); a preference for particular food (techniques); a
distinctive set of flavor, textural, and visual characteristics (Aesthetics); a
set of rules for consuming food (ritual); and an organized system of producing
and distributing the food (infrastructure). Embedded in these components are a
set of ideas, images, and values (ideology) that can be "read" just like any
other cultural "text."
