Rasam powder is another Indian spice blend and like many traditional spice blends, its history is not well documented. What is known about rasam powder is that it is used to flavor a dish called rasam, which is a South Indian soup made with lentils. It is also known that rasam’s roots lie in Tamil Nadu and Karnataka and has made its way into surrounding states. It is viewed as a comfort food for many in this region and is also a popular dish for weddings.
Rasam is a dish of the Sourashtra people, a community that migrated from Gujarat and elsewhere to Tamil Nadu.
Rasam powder can be found in many Indian markets as a blend. Despite the convenience of a pre-blended powder, many Indian cooks prefer to put their own rasam powder blend together.
