Lime leaf

Lime leaves, also known as Kaffir lime leaves, are the aromatic leaves of the Kaffir lime tree, a citrus fruit native to Southeast Asia. They are typically used fresh or dried in cooking, and are often bruised or finely shredded to release their potent fragrance and flavour.

Lime leaves are primarily used to impart a distinct citrusy, floral aroma and flavour to dishes. They are a staple in many Southeast Asian cuisines, commonly found in curries, soups, stir-fries, and marinades, adding a fresh, zesty note.

Lime leaf is not considered a food additive in the UK and is used as a flavouring ingredient. There is no specific regulatory status on the Register of Food Additive Authorisations for lime leaf itself. Evidence on specific health effects from consuming lime leaf at typical dietary levels is limited. No notable controversies are widely reported regarding its use in food.
