The main ingredient found in traditional curry is usually a blend of spices, but in terms of a foundational element, it varies by region. Generally, a combination of spices such as turmeric, cumin, coriander, and chili powder create the distinct flavor profile of curries. In many cases, these spices are mixed with a base of tomatoes, onions, and garlic or ginger, as well as a source of protein or vegetables. Each type of curry, whether Indian, Thai, or Caribbean, has its own unique combination of ingredients that define its taste, allowing for a wide range of culinary diversity.
