What is "rasam"?

Rasam is a traditional South Indian soup that is known for its tangy and spicy flavor. The soup is typically made with a base of tamarind juice, tomatoes, and spices such as cumin, coriander, and black pepper. The soup may also include lentils or other legumes, which give it a rich and hearty texture. Rasam is often seasoned with fresh curry leaves and mustard seeds, which add a unique and aromatic flavor to the dish. The soup is usually served hot and is often enjoyed as a starter or as a side dish to rice or other South Indian dishes.
