In a non- stick pan, add the curd, water, salt, jeera, chilli powder, baking powder (if using ) and green chillies.
Mix all the ingredients and bring to a rolling boil.
Once the mixture boils, add the ragi flour and stir well as you add the flour.
Stir continuously and get rid of all the lumps. The easier way is to get the pot off the flame to add the flour gradually and mix well breaking the lumps, only be quick. Maybe next time I will take kiddos suggestion and use the immersion mixer.
Cook covered on low flame for about 5-10 until the mixture leaves the side of the pan.
Add coriander leaves, drizzle the oil if using and dish up immediately.
