Rasam as everyone is aware is a very popular south indian soup prepared out of tomato, lentils, tamarind extract, pepper and many other flavours. They are generally had with rice or can be taken as a soup with some croutons or bread sticks. It tastes great as an appetizer too. There are many variations to this delicious and refreshing soup. Today i prepared using both tomatoes and tuvar dal (split pigeon pea lentil). It is recommended to have it piping hot for all the health benefits like common colds and congestion.
