Moringa oleifera is the most widely cultivated species of the genus Moringa, which is the only genus in the family Moringaceae. English common names include: moringa, drumstick tree (from the appearance of the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben oil tree, or benzoil tree (from the oil which is derived from the seeds). It is a fast-growing, drought-resistant tree, native to the southern foothills of the Himalayas in northwestern India, and widely cultivated in tropical and subtropical areas where its young seed pods and leaves are used as vegetables. It can also be used for water purification and hand washing, and is sometimes used in herbal medicine.
Moringa has numerous applications in cooking throughout its regional distribution. It may be preserved by canning but is often made into a variety of curry dishes by mixing with coconut, poppy seeds, and mustard or boiled until the drumsticks are semisoft and consumed directly without any extra processing or cooking. It is used in curries, sambars, kormas, and dals, although it is also used to add flavor to cutlets and other recipes.
The fruit meat of drumsticks, including young seeds, is used for soup. Young leaves can either be fried with shrimp or added as a topping in fish soup. Several traditional dishes use leaves (sluc) of the moringa tree known as daum m’rum, such as korko (a mixed vegetable soup). As it is a favorite vegetable, Cambodians traditionally grow moringa trees close to their residences.
