Soak tamarind in 1/2 cup warm water and extract the juice. To this add the crushed tomatoes.
Add this to the coconut-milk and dal mixture. To this add the crushed garlic and rasam powder. Stir well.

Next add the coconut-milk mixture. Reduce the flame to lowest possible. Do not allow this mixture to boil.
Let this be on the heat, until it starts to froth well.

When the rasam comes to a boil, pour it into the bowl and cover with a lid and serve after 15 minutes. Serve hot as an accompaniment with rice.
