Curry Leaf (Kari)

Murraya koenigii
Family: Rutaceae (citrus family).
Kari (or curry) leaf (called kariveppilai in Tamil) is grown all over India and has been used for centuries in South India and Sri Lanka as a flavoring for curries, chutneys, vegetables, and beverages. South Indian traders introduced it into Malaysia, Burma, and Singapore. When the British were in India, they called it curry leaf, naming it after the seasoned sauce (called kari in Tamil) that it was added to.
Origin and Varieties
Indigenous to India and cultivated all over India, including the Himalayas, Sri Lanka, Southeast Asia, and the United States (California and Florida).
Spice Description
Kari leaf is very fragrant when used fresh, but it loses its flavor intensity when dried. The fresh or dried leaf is used whole, crushed, and chopped. Properties: the fresh leaf has a spicy, strong piney-lemony aroma, and a slightly tangerine peel-like taste.
Culinary Uses
It is an essential spice in South Indian, Sri Lankan, and Malaysian curries, dals, samosas, dosai fillings, chutneys, snacks, sambars, soups, breads, and vegetables. Kari leaf is popularly used in South Indian vegetarian and fish dishes and Sri Lankan meat and chicken curries. Kari leaves par well with mustard seeds, turmeric, ghee, cumin, coriander, fenugreek, dals, ginger, garlic, tomatoes, and yogurt. It provides a certain zest to yogurt-based salad dressings and vegetable dishes, such as fried cabbage, lentils, beans, okra, or eggplant. It is usually removed before the food is eaten.
Kari leaf also provides a distinct spicy flavor to cold dishes and buttermilk. It gives a more intense flavor and crunchiness when it is toasted in oil or ghee, and this mixture is then added to many vegetarian foods. Sometimes it is toasted, ground, or crushed to season or garnish soups, sambars, and curries.
Kari leaf can be kept frozen or refrigerated in a plastic bag for about two weeks. Freezing better retains its flavor, but its color changes to black. To retain its fresh flavor, it is best not to remove the leaves from its branches until ready to use. Spice Blends: curry blends, sambar podi, rasam podi, chutney blends, and fish curry blends.
