Kaffir lime leaves, or bai makrut, are another essential component in Thai cuisine, prized for their intense citrus fragrance. These dark green, glossy leaves are usually torn or shredded to release their aromatic oils, which add a fresh, tangy note to dishes. They are most commonly used in curries, soups, and salads, such as the iconic Green Curry (Gaeng Keow Wan) and Massaman Curry. Beyond their flavour, kaffir lime leaves also add an appealing aroma, enhancing the overall sensory experience of a dish. They are often removed before serving at your typical Koh Samui restaurant, as their tough texture makes them difficult to chew.
