Mam, Just now I tried making the batter. I made rice powder at home. As you said I took one bowl rice powder added garlic and chilli flakes and rest of the things. Added only half cup of water. And the batter was thin and when I poured it in the pan it was running. And the rotti was hard. I was very upset. I kept the remaining batter in the fridge. I don't know what to do with it.
