Kaffir lime leaves are a highly aromatic herb widely used in Southeast Asian cuisines, especially in curries, soups, and stir-fries. Known for their intense citrus fragrance and slightly floral notes, they infuse dishes with a distinctive, refreshing flavour. Typically used whole or finely sliced, kaffir lime leaves are best added during cooking to release their aroma, making them an essential ingredient for creating authentic and vibrant dishes.
