This document discusses the evolution of culinary culture and cooking techniques from early humans. It covers how early humans ate raw and fermented foods before controlling fire, and how basic cooking methods developed using tools like skewers and hot stones. The document also examines how the five basic tastes (sweet, salty, sour, bitter, umami) evolved significance for humans. It introduces the concept of the "culinary triangle" to show how foods can be prepared in raw, cooked, or fermented states. Modern food processing techniques are noted for removing foods from their cultural contexts.
