Classic Tomato Rasam is a popular South Indian soup made with tomatoes, tamarind, and a blend of spices. It is tangy, spicy, and bursting with flavors. This rasam is usually served as a comforting soup or as a side dish with rice and papadum. The recipe involves tempering mustard seeds, cumin seeds, curry leaves, and red chilies in ghee, and then adding tomatoes, tamarind extract, rasam powder, and other spices. The rasam is simmered until it reaches a soupy consistency and is garnished with fresh coriander leaves. It is a perfect dish to warm you up on a cold day.
