Citrus hystrix is a thorny bush, 6 to 35 feet (1.8 to 10.7 m) tall, with aromatic and distinctively shaped "double" leaves.The makrut lime is a rough, bumpy green fruit. The green lime fruit is distinguished by its bumpy exterior and its small size (approx. 4 cm (2 in) wide). The rind of the kaffir/makrut lime is commonly used in Lao and Thai curry paste, adding an aromatic, astringent flavor. The zest of the fruit is used in creole cuisine to impart flavor in "arranged" rums in the Martinique, Réunion island and Madagascar. However, it is the hourglass-shaped leaves (comprising the leaf blade plus a flattened, leaf-like leaf-stalk or petiole) that are used most often in cooking. They can be used fresh or dried, and can be stored frozen.
