2. Soak these grains in 2 cups of water for about 3 hours.
3. Grind this in batches in a processor / blender with the curry leaves, ginger, green chillies and red chillies using the water it was soaked in to help in the grinding process.
4. This does not have to be ground very smooth, the grains could be of the texture of semolina (cream of wheat)(rava).

12. Proceed with the rest of the batter in the same manner.
