Kaffir Lime

What Is Kaffir Lime?

Kaffir lime (Citrus hystrix) is a citrus fruit with a rough rind, native to Southeast Asia. Its most valuable part in cooking is its glossy, extremely aromatic, double-lobed leaves that look almost like two leaves joined end to end.

When crushed or cooked, the leaves release an intense, refreshing citrus aroma; the rind is also used for zest. They are essential aromatics in curries, soups, and herb mixtures in Thai, Indonesian, and neighboring cuisines.

Kaffir Lime Nutrition Facts

Because kaffir lime leaves are used in very small amounts as an aromatic ingredient, their contribution to a meal’s nutritional value is negligible; therefore, no detailed nutrition table is provided. Their value comes from their intense citrus aroma.

How to Use Kaffir Lime

Kaffir lime leaves can be added whole after lightly crushing them and removed at the end of cooking, or the central vein can be removed and the leaves finely chopped and left in the dish. Because their aroma is intense, only a few leaves are needed.

This is general information; kaffir lime is a food, not a medical treatment.

How to Choose Kaffir Lime

Good kaffir lime leaves are glossy, dark green, firm, and strongly citrus-scented when crushed, with no yellowing. Avoid wilted, dried, or weakly scented leaves.

• They should be glossy, dark green, and firm.
• They should have a strong citrus aroma.
• They should not be wilted or yellowed.

How to Store Kaffir Lime

Store fresh kaffir lime leaves for a short time in a sealed container in the refrigerator. For longer storage, freeze them; frozen leaves retain most of their aroma and can be added directly to cooking.

Using Kaffir Lime in the Kitchen

Kaffir lime leaves are most often used in Thai and Indonesian curries, soups such as tom yum, rice dishes, and marinades. Whole leaves are added for aroma and removed; very finely chopped leaves can remain in the dish and add a refreshing citrus note.

Should You Use the Leaf or the Rind?

The leaves are used most often; the grated rough rind is aromatic too. The juice is sour and scant, so the leaves are the part most valued in cooking.
