Curry Leaves
The curry tree (Murraya koenigii or Bergera koenigii) is a tropical to sub-tropical tree in the family Rutaceae (the rue family, which includes rue, citrus, and satinwood), which is native to India and Sri Lanka.
Its leaves are used in many dishes in India, Sri Lanka , and neighbouring countries. Often used in curries, the leaves are generally called by the name 'curry leaves', although they are also literally 'sweet neem leaves' in most Indian languages (as opposed to ordinary neem leaves which are very bitter and in the family Meliaceae, not Rutaceae).
The leaves are highly valued as seasoning in southern and west-coast Indian cuisine, and Sri Lankan cuisine especially in curries, usually fried along with the chopped onion in the first stage of the preparation. They are also used to make thoran, vada, rasam and kadhi. In their fresh form, they have a short shelf life and do not keep well in the refrigerator. They are also available dried, though the aroma is largely inferior. Leaves can also be harvested from home-raised plants as it is also fairly easily grown in warmer areas of the world, or in containers where the climate is not supportive outdoors.
The leaves of Murraya koenigii are also used as an herb in Ayurvedic medicine.
Although most commonly used in curries, leaves from the curry tree can be used in many other dishes to add flavour. In Cambodia, Khmer toast the leaves in an open flame or roast it until crispy and then crush it into a soured soup dish called maju krueng.
Because of its aromatic characteristic properties, the plant has uses in soap making, body lotions, potpourri, scent, air fresheners, body fragrance, perfume, bath and massage oils, aromatherapy, towel scenting, spas and health clinics, incense, facial steams or hair treatments.
