Heat a little oil in a pan and add urad dal, channa dal, and red chilies. Roast till golden brown and transfer to a plate to cool.

To the same pan, add chopped tomatoes and grated radish and saute.

Saute till the tomato is mushy and the raw smell of radish is gone.

Add a small bit of tamarind and sauté for a minute. Let it cool.

Take this and the dal mixture along with salt to taste and grind to a semi coarse paste adding water only if needed.

Serve as a side for steamed rice or Idli / Dosa
