The main ingredient in a traditional curry varies widely depending on the recipe and regional variations, but it frequently includes a blend of spices and herbs. Typically, these spices include turmeric, cumin, coriander, and chili powder, which provide a rich flavor profile. Additionally, the base of many curries is made from meats, fish, or vegetables, often cooked in a sauce that can be creamy or tomato-based. Coconut milk is also a common ingredient in certain types of curries, especially in Southeast Asian cuisine. Overall, the harmony of spices and other components defines the essence of a curry dish.
