Curries may contain fish, meat, poultry, or shellfish, either alone or in combination with vegetables and are very popular in today’s modern cuisine.
There are many varieties of dishes called ‘curries’. For example, in original traditional cuisines, the precise selection of spices for each dish is a matter of national or regional cultural tradition, religious practice, and, to some extent, family preference. Such dishes are called by specific names that refer to their ingredients, spicing and cooking methods. Spices are used both whole and ground; cooked or raw, and they may be added at different times during the cooking process to produce different results. The main spices found in most curry powders of the Indian subcontinent are coriander, cumin, and turmeric; a wide range of additional spices may be included depending on the geographic region and the foods being included (fish, lentils, red or white meat, rice, and vegetables). Curry powder, a commercially prepared mixture of spices, is largely a Western creation, dating to the 18th century. Such mixtures are commonly thought to have first been prepared by Indian merchants for sale to members of the British Colonial government and army returning to Britain. Source: Wiki
