Protein Idli Recipe

This is my mom's recipe to decrease the sugar hike in the blood after eating soft idlis made from rice alone.

Prepare regular idli batter:
2 cups idli rice, 1/2 cup urad dhal - soak for 3 hours and grind them along with a spoonful of methi seeds. Ferment them for one night.
Prepare adai batter:
Take 1/2 cup of:-  thuvar dal, channa dal, urad dal, soya, horse gram, moong dal, green moon dal + spoonful of methi seeds, 1" ginger and 2 g.chillies (optional). Soak them for 3 hours and grind them. No fermentation is required for this batter. So I immediately keep them in the fridge when I prepare them along with the idli batter (that requires overnight fermentation).
Protein idlis:
Next day, mix both the batter and make soft idlis which are really healthy with a high protein content and does not hike up the blood sugar.
