Kaffir Lime

Kaffir lime, also known as makrut lime, is a citrus fruit native to Southeast Asia. The leaves and rind are commonly used in cooking for their distinct, strong citrus aroma and flavor. The fruit itself is typically not eaten whole due to its very tart juice and thick, bitter rind.

Kaffir lime leaves and zest are primarily used to add a unique, fragrant citrus note to dishes. They are a staple in Thai, Laotian, and Indonesian cuisine, found in curries, soups, stir-fries, and marinades. Manufacturers use it as a natural flavoring agent to enhance the taste profile of savory and sometimes sweet products.

Kaffir lime is generally recognized as safe (GRAS) by the FDA when used as a flavoring. It is not typically consumed in amounts large enough to pose a health risk. International bodies like JECFA have evaluated citrus flavors, but specific evaluations for kaffir lime's health impacts at typical consumption levels are limited. Evidence regarding specific health benefits or risks is not robust.
