Vegetarian cheese by John Spottiswood.

vegetarian cheese When making cheese, milk is curdled with the help of rennet, an enzyme that occurs naturally in the stomach of animals. Many vegetarians object to eating cheese made with natural rennet, since its production involves the slaughter of animals. Fortunately, a lot of fine cheese is now made with vegetable rennet, which is derived from fungi, bacteria, or plants. Unfortunately, the type of rennet used isn't always marked on the cheese label. Some stores help out by adding their own labels.
