1/2 of a medium cabbage, chopped finely
1 cup idli rava
1 cup grated coconut
5 to 6 roasted red chillies
1 marble sized tamarind
1/4 tsp haldi
1 tsp hing
Soak idli rava in water for 15 minutes. [The water should just cover the top].
Grind grated coconut, red chillies, turmeric powder and tamarind, with very little water - just enough to get a smooth paste. Drain any extra water from the idli rava, add to the above and grind again. Do not add too much water. The batter should be thick.
Add salt and hing and mix well. Add chopped cabbage into the batter [only as much cabbage as the batter can accommodate]. Shape into balls.
Grease the steamer basket lightly. Place undis atleast half an inch apart as they will slightly increase in size. Steam undis for 25 minutes, or till toothpick inserted comes out clean. [You can even use an idli stand to steam].
To serve - In a bowl, pour some coconut oil, mix a pinch of hing. Pour on top of the undi.
