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.
The rind of the makrut lime is commonly used in Lao and Thai curry paste, adding an aromatic, astringent flavor.[5] 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. The leaves are widely used in Thai[5] 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.[9] The juice is generally regarded as too acidic to use in food preparation. In Cambodia, the entire fruit is crystallized/candied for eating.[4]
