Native to Thailand, kaffir lime is a key ingredient in Thai cooking, offering an amazing aroma and distinctive taste. Both the fruit and its leaves are used extensively in Thai cuisine. The leaves have a zesty, citrus flavour, which is particularly important in soups and curries. Kaffir lime leaves are often added whole to broths and removed before serving to infuse dishes with a fresh, bright flavour.

In Samunprai, kaffir lime is revered for its cleansing properties and is commonly used in traditional herbal steam treatments to detoxify the skin. The rind and juice are also used in Thai dips and salads, while the fruit’s essential oils have antibacterial properties and are often used in natural remedies to promote healthy digestion and immune function.
