Wash and soak poha in curd for 3-4 mins . Since its thin variety , it will become mushy . Mash nicely.
Add rice rava , little soda ( if you want ) and salt to it . Mix and allow to sit for 10 mins. poha n rice rava will drink in all the liquid content . Add water as required and get idli batter consistency ( little thicker than milkshake ) . instant idli batter is ready , fermentation not required .
Heat water in a steamer.Grease idli molds with oil .Pour the batter into idli stand.
Steam for 12-15 mins on medium flame.Prick a tooth pick,if it comes clean it means its done.Allow it to cool a bit and remove from molds using a spoon or knife.
Thats it soft, spongy and instant poha Idli's are ready to serve. Serve withChutney / Sambar /Gojju/ Chutney Powder.
Notes
If you want you can do the batter before hand n do idlis in the morning . You can keep in fridge / outside to ferment a bit . Your choice . Still comes out good .
I feel coz of poha and no fermentation , these idlis are little bland in taste . So a spicy side dish will take these idlis to a new level .
