Cheese

Cheese is milk made more concentrated, more durable, and more flavorful through controlled coagulation of casein proteins, removal of whey, and — in aged cheeses — prolonged enzymatic breakdown of proteins and fats. It is one of the oldest fermented foods, with archaeological evidence dating to ~2300 BCE, and one of the most diverse: France alone produces several hundred distinct varieties, each a product of local milk, climate, microbes, and tradition.
