Murraya koenigii (L.) Sprengel |
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).
It is a small tree, growing 4–8.7 m (13–31 feet) tall, with a trunk up to 81 cm (32 in) diameter. The aromatic leaves are pinnate, with 11–21 leaflets, each leaflet 2–4 cm (0.79–1.57 in) long and 1–2 cm (0.39–0.79 in) broad. The plant produces small white flowers which can self-pollinate to produce small shiny-black berries containing a single, large viable seed. Though the berry pulp is edible—with a sweet but medicinal flavour—in general, neither the pulp nor seed is used for culinary purposes.
The species name commemorates the botanist Johann König. The genus Murray commemorates Swedish physician and botanist Johann Andreas Murray who died in 1791.
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.
