Kaffir lime leaves also known as Makrut Lime Leaves are an important ingredient in Thai and other Southeast Asian cuisines. Known for their strong aroma, these leaves enhance the flavor of various Thai soups, curries, and stir-fries. The leaves are distinctive, with a dark green, glossy side and a lighter, textured side. They are available in fresh, frozen, and dried forms.
What Are Kaffir Lime Leaves?
Makrut limes (Citrus hystrix) differ from regular limes in their bitter taste and bumpy skin. In Thailand, these limes are primarily used for making household cleaning products rather than for consumption. However, the leaves of the makrut lime are highly aromatic and can be used in cooking when thinly sliced or cooked. These leaves are unique in their hourglass shape, with each stem ending in two leaves. Kaffir lime leaves are available in fresh, frozen, and dried forms.
Uses of Kaffir Lime Leaves
Kaffir lime leaves serve a similar role to bay leaves in Asian cuisine. They can be added whole to Thai curries, soups, and stir-fries, and should be removed before serving. Alternatively, you can finely slice the leaves and incorporate them into spice pastes or use them as a flavorful topping for various dishes.
Cooking with Kaffir Lime Leaves
Adding Kaffir lime leaves to your recipes is simple and requires minimal preparation. Remember that each joined pair of leaves counts as two separate leaves. If the leaves are still attached to the stem (also known as the rib or vein), you can remove it by folding the leaf in half and pulling the stem downward. This will leave you with a whole leaf without the rib. You can use the leaf as is or cut it into thin, sliver-like pieces using clean scissors. Alternatively, you can remove the rib with a paring knife, which will leave you with two separate leaf pieces.
Frozen lime leaves can be used directly from the freezer or quickly thawed by rinsing them under hot water to release their fragrance. Dried leaves should be crushed or ground before use, or they can be rehydrated. Keep in mind that dried leaves are less aromatic and flavorful compared to fresh or frozen ones. If the dried makrut lime leaves have lost some of their fragrance due to the drying process, consider using a larger quantity to achieve the desired flavor.
What Flavors Do Kaffir Lime Leaves Add?
