Lemon tree (Citrus hystrix)

Other names: Kaffir lime, Kaffir lime, Mauritian papeda

The lemon tree, also known as Kaffir lime, Kaffir lime or Mauritian papeda, is a species of citrus tree found mainly in Southeast Asia. Its scientific name is Citrus Hystrix. This not-very-large tree, which can reach a height of up to three metres, is characterised by its oval-shaped fruit with a hedgehog-like green rind similar to the bumps of a lime.

Kaffir lime fruits are mainly used in Thai and Indonesian cuisine. The orange-sized, green fruit yields an essential oil that is an important ingredient in perfumes and topical remedies, such as for head tics. The juice of the lemon tree has a slightly bitter taste and is used to flavour dishes. The leaves also have a strong citrus aroma and are a popular ingredient in Asian cuisine, where they are added to soups, marinades and curry sauces. Lemon oil is also used in aromatherapy and, in some cases, medicine, particularly for its soothing and antibacterial properties. The rind of the fruit is dried and ground and used as a spice. The tree also produces flowers that are used in traditional medicine.
