Herb and Spice of the Week - Kaffir Lime

Citrus hystrix

The kaffir lime (Citrus hystrix), sometimes referred to in English as the makrut lime (see below), is a fruit native to Indochinese and Malesian ecoregions in India, Nepal, Philippines, Bangladesh, Indonesia, Malaysia and Thailand, and adjacent countries. It is used in Southeast Asian cuisine.







Citrus hystrix is a thorny bush, 5-10m 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 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, RĂ©union 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. The leaves are widely used in Thai and Lao cuisine (for dishes such as tom yum), and Cambodian cuisine (for the base paste "Krueng"). Makrut lime leaves are used in Vietnamese cuisine with chicken to add fragrance. They are also used when steaming snails to decrease the pungent odor while cooking. The leaves are also used in Indonesian cuisine (especially Balinese cuisine and Javanese cuisine), for foods such as Soto ayam, and are used along with Indonesian bay leaf for chicken and fish. They are also found in Malaysian and Burmese cuisines. The juice is generally regarded as too acidic to use in food preparation. In Cambodia, the entire fruit is crystallized/candied for eating.








The juice and rinds are used in traditional Indonesian medicine; for this reason the fruit is referred to in Indonesia as jeruk obat ("medicine citrus"). The oil from the rind has strong insecticidal properties. In South India the lime is juiced and the rind is filled with turmeric powder and sea salt and dried under hot Sun. This is used as an accompaniment for "Kanji" when sick.

The juice finds use as a cleanser for clothing and hair in Thailand and very occasionally in Cambodia. Lustral water mixed with slices of the fruit is used in religious ceremonies in Cambodia.








Citrus hystrix is grown worldwide in suitable climates as a garden shrub for home fruit production. It is well suited to container gardens and for large garden pots on patios, terraces, and in conservatories.
