I'm disappointed at the lack of relevance of these confectionary-related names. "Cookie" means "small cake" (in other languages, the word "cook" and "cake" are the same word). "Biscuit" means "twice cooked" (from Latin bis (twice) and French cuit (cooked)). It's already disappointing that cookie and biscuit are considered synonymous but simply American vs British when there is a meaningful distinction. Cookies are just small cakes, biscuits are small cakes that are baked again to dry them out. These technologies seem to have nothing to do with the foods, though.
