Cheese is a dairy product made by coagulating milk protein, resulting in a range of flavors, textures, and forms. It's primarily made from cow's milk, but can also be derived from the milk of sheep, goats, buffalo, reindeer, camels, and yaks. The basic cheesemaking process involves culturing milk for varying lengths of time, and adding a coagulant to separate solids from the liquid. Coagulants are typically acids like vinegar, or rennet, an enzyme found in cows' stomachs.
