The main ingredient found in cheese is milk. Cheese is produced by coagulating milk proteins, primarily casein, which separates the curds from the whey. Various types of milk, including cow's, goat's, or sheep's milk, can be used to produce different types of cheese. The milk undergoes a fermentation process, often using specific bacteria or enzymes, to develop the desired flavor and texture. After the curds are formed, they are drained, pressed, and may be shaped depending on the type of cheese being made. Aging is also a critical component in cheese production, allowing flavors to deepen and develop.
