Nandu Rasam / Spicy Crab Soup is one among the delicious non-vegetarian soup. It is very healthy and also good enough to boost your immunity. Crabs are considered to be high in protein and low in fat & calories. This rasam is a best way to beat off cold and flu. We use small crabs that are thin in texture, but with delicious taste and wonderful aroma. This can be served directly as a soup or with steamed rice as you would normally eat rasam sadam (rice).
