🍲 About Kollu Rasam

A tangy, peppery rasam prepared using horse gram and traditional South Indian spices.

Kollu Rasam is a traditional Tamil Nadu dish made using kollu, also known as horse gram, along with tamarind, tomatoes, garlic, black pepper, cumin and other spices. It is a thin, tangy and peppery broth commonly prepared in Kongu Nadu, the western region of Tamil Nadu. Horse gram is an important ingredient in traditional rural cooking, where it is valued for its nutritional content and distinctive earthy flavour. The rasam can be served with steamed rice or enjoyed on its own as a warm soup. Its combination of horse gram, aromatic spices and tamarind creates a flavourful dish that complements everyday home-cooked meals. Recipes vary between households: some use the strained cooking liquid from boiled horse gram, while others add ground horse gram or a portion of the cooked legumes to create a fuller texture. Kollu Rasam reflects the practical, ingredient-conscious cooking traditions associated with Kongu Nadu and remains a familiar preparation in households that use horse gram regularly.

👨‍🍳 Preparation Method

Horse gram is washed and cooked in water until soft. The cooking liquid is reserved for the rasam, and some recipes also use a small portion of the cooked horse gram. Tamarind is soaked in water and its extract is prepared, often with chopped tomato, turmeric and salt. Black pepper, cumin and garlic are crushed or ground to release their aroma. The tamarind mixture is simmered with the horse gram liquid and the spice mixture until the flavours combine. A tempering is prepared by heating oil and adding mustard seeds, dried red chilli, curry leaves and asafoetida. This tempering is poured into the rasam, which is heated gently and removed from the stove once aromatic. Fresh coriander may be added before serving. Household methods and ingredient proportions vary, and the rasam is generally not boiled vigorously for a long time after the spices have been added.
