Rasam is a spicy South Indian soup-like dish. It is usually served as a side dish with rice. In a traditional South Indian meal, it is part of a course that includes sambar rice. Rasam has a distinct taste in comparison to sambar due to its own seasoning ingredients and is fluid in consistency. Chilled prepared versions are marketed commercially as well as rasam paste in bottles.
