Dal tadka or tadkewali dal is a traditional lentil-based dish originating from the northern parts of India. Although there are variations, the dish is usually prepared with toor dal (split yellow pigeon peas), garlic, ginger, onions, tomatoes, garam masala, chili peppers, ghee, cumin, coriander, turmeric, red chili powder, and fenugreek leaves.
These ingredients are cooked and mixed with tadka (tempering), consisting of spices such as asafoetida, chili peppers, and garlic that are cooked in ghee. Once prepared, dal tadka is usually garnished with coriander leaves and served hot with jeera rice and roti on the side.
