About the recipe

This tomato onion gotsu is one that my Mom used to make to accompany a lentil and rice dish called pongal.  Mom’s simple rice pongal along with her tomato gotsu were always a hit in our home and was truly comfort food.  One can serve gotsu warm or at room temperature over your favorite rice dish, or even over chicken or fish.


For a simple and quick tomato and onion gotsu give this recipe a try.
