The ingredient in parmesan that isn't vegetarian is rennet, an enzyme complex used in the cheese-making process to curdle milk. Typically derived from the stomachs of young ruminant animals like calves, rennet is crucial for giving Parmesan its unique texture and flavor. For vegetarians, seeking out parmesan-style cheeses made with microbial or vegetable rennet substitutes is a better option, ensuring the choice aligns with vegetarian dietary restrictions.
