Purut

Purut refers to a type of fruit, specifically the kaffir lime, scientifically known as Citrus hystrix. This small, bumpy citrus fruit is native to Southeast Asia and is widely used in cuisines across the region, particularly in Thai, Indonesian, and Malaysian cooking. The leaves of the kaffir lime tree are more commonly used than the fruit itself in many culinary applications. These leaves are intensely aromatic and are a staple ingredient for adding a distinctive fragrance and flavor to curries, soups, and stir-fries. The zest of the fruit can also be used, offering a potent citrusy note.

The essential oil extracted from the leaves and rind of the kaffir lime is also utilized. It has a strong, refreshing aroma and is found in many traditional remedies and modern aromatherapy products. In some regions, the juice of the fruit is used as a cleaning agent due to its acidic properties. While the fruit itself is not typically eaten raw due to its sourness and bitter pith, its essential oil and leaves are highly valued for their unique sensory qualities. The plant is characterized by its distinctive double-lobed leaves and thorny branches.
