The plant

change

The plant is a very thorny bush with aromatic leaves. The oil obtained from the rind of the fruit can be used as an insecticide. The plant is well suited to being grown in a container. The green fruits are different from other limes because of their bumpy and rough exterior. They are also quite small, about 4 centimetres across. The leaves are shaped like an hourglass. The leaves and the leaf-shaped stem are widely used in the cuisine of Cambodia, Thailand and Laos.

Citrus x hystrix leaves are also popular in Cambodia but less so in Vietnam. Malay, Burmese and Indonesian (especially Balinese and Javanese; see also Indonesian bay leaf) cuisines use them sporadically with chicken and fish.

The leaves can be used fresh or dried and can be stored frozen.

Although the most common product of the Citrus x hystrix tree is its leaves (which give a sharp Lime/neroli flavour to Cambodian base paste known as Krueng, Thai dishes such as tom yum and Indonesian food such as sayur assam - literally sour vegetables), the juice and rind of the small, dark-green gnarled fruit (known as jeruk obat - literally medicine citrus) are used in traditional Indonesian medicine.

The zest is widely used in Creole cuisine and to impart flavour to "arranged" rums on Réunion and Madagascar.

Terminology

change

The Oxford Companion to Food (ISBN 0-19-211579-0) recommends that the name kaffir lime should be avoided in favour of makrut lime because Kaffir is an offensive term in certain cultures and also has no clear reason for being attached to this plant. However kaffir lime appears to be much more common.
