Rennet is a complex set of enzymes used in cheese-making to coagulate milk, turning it from liquid to the solid curds needed to produce cheese. It typically comes from the stomachs of young ruminants, but there are also vegetable and microbial alternatives to accommodate vegetarian diets. Its primary purpose is to separate the milk into solid curds and liquid whey, a crucial step in the cheese-making process.
