So what it Rennet?

Today I figured out that most cheeses have rennet in them. Rennet is an extract from the fourth stomach of a young cow. The calf uses the rennet to digest its mothers milk. Most people don't list rennet as it ingredient. Several plants produce natural rennet compounds. But don't worry cheeses with alternatives to rennet are available. Some cheeses don't need rennet as an ingredient cheeses like cottage cheese, ricotta, and some varieties of mozzarella.
