Kaffir lime leaves are small to medium in size and oblong in shape. averaging 3-5 centimetres in diameter and 8-12 centimetres in length. The top of the thick leaves is glossy and deep green, while the underside of the leaves is porous and a pale, matte green. Kaffir lime leaves grow in pairs and grow in a double leaf formation, which means two leaves grow on either side of the stem and appear to mirror each other. There is a prominent central midrib or vein and the tips of the leaves can be slightly rounded or very pointed. Kaffir lime leaves have a strong citrus taste and aroma that is said to be a blend of mandarin orange, lemon, and lime.
