The main ingredient in curry is typically a blend of spices, with turmeric playing a focal role. Turmeric gives curry its characteristic yellow color and contributes to its earthy flavor. Depending on the variety of curry, additional spices such as cumin, coriander, ginger, and chili may be included, each adding depth and complexity. While curry can also feature various proteins and vegetables, the spice blend is what fundamentally defines it. Different cultures, especially in South Asia, have their unique interpretations of curry, leading to a rich diversity in flavors and preparations across cuisines.
