Chettinadu Rasam is a flavorful and tangy soup made with tamarind, tomatoes, and a blend of spices. The rasam is cooked until it reaches a thin consistency and is then tempered with mustard seeds, curry leaves, and dried red chilies. It is typically served as a starter or as a side dish with rice and other South Indian dishes. The combination of tangy tamarind and aromatic spices makes this rasam a comforting and refreshing dish.
