Rennet is an enzyme found in the stomach of young mammals and has been used for thousands of years in cheese making. This extract from the dried stomachs of goats, sheep, and cattle is the original rennet, not some manufactured laboratory chemical. Certain plants contain similar enzymes and have been used to produce vegetable rennet. Genetic engineering has also been used to develop microbes that produce what is known as microbial rennet. All of these types of rennet work very well for making cheese. Citric acid can be used to make soft cheese, but to make hard cheese, some type of rennet is required. There is simply no substitute.
