Here is the recipe
For the batter
Raw rice - 2 cups
salt
For koozhu
Tamarind - marble sized
Ground batter - 1 tblspn
Preparation
Wash and soak raw rice for 3 hrs.
Grind to a fine paste using little water. If you add more water, it will be difficult to grind to a smooth paste.
Preparing the koozhu
Take a tablespoon of the ground paste and mix with the tamarind extract. Add water to make it to 1 cup. It is fine If it is little more also.
Boil the mix on stove top with constant stirring. It has a tendency to form lumps and stick to the bottom.
Boil the mix on stove top with constant stirring. It has a tendency to form lumps and stick to the bottom.
As it starts boiling, It will begin to thicken. Stop when it reaches a semi solid stage.
This is called koozhu (it will resemble the baby food - koozhu).
The color of the koozhu depends on the tamarind color. I used the fresh tamarind of the season. So it has not turned dark.
Prepare the batter
When cool, mix the koozhu to the ground batter.
Batter consistency should be thinner than the usual dosa batter.
When you pour the batter on to tawa, pour in a circular pattern and later spread lightly with the laddle.
Add oil on sides.
When cooked flip over and cook the other side too.
It is slightly sticky because of the tamarind added. You will be able to flip over without much difficulty.
I feel the koozhu is added to soften the dosa since only raw rice is used.
