The key ingredient in traditional Indian curry is often a blend of spices, with turmeric being one of the most significant. This rich yellow spice not only imparts a beautiful color to the dish but also contributes to its unique flavor profile. Other common spices used in Indian curry include cumin, coriander, ginger, and chili pepper, which together create a complex tapestry of flavors. While the base of the curry may include ingredients like meat, legumes, or vegetables, the spices are what define the dish and vary greatly between different regional cuisines within India.
