In a bowl, take the rice with urad dal, poha, sago, and methi, and wash well.
I usually wash for 2 go 3 times until the water turns clear.
Fill again with 1/2 inch extra water to the ingredients, cover, and let it soak for at least 4 to 5 hours.
Once the resting time is over, get the grinder cleaned and ready.
Drain the water and grind to a smooth batter adding water as required for the batter to become soft.
When the batter is smooth, transfer to a tall bowl, add salt and mix well.
Let the vessel be double the amount of batter you get, as it will ferment to double its size.
Let it ferment overnight.
