The main ingredient in traditional Indian curry is a blend of spices, often referred to as "curry powder," but the exact mix can vary widely. Common spices include turmeric, cumin, coriander, and garam masala, which offer rich flavors and colors to the dish. While curry can include various meats, seafood, or vegetables, the foundation is laid with this spice mixture, often combined with onions, garlic, and ginger. Each region in India has its unique approach to curry, resulting in a plethora of delicious interpretations.
