In a bowl, mix together sooji, beetroot, yoghurt, salt, ginger, turmeric powder, cumin powder, kasuri methi, 1 tbsp. oil and green chilies. Add enough water to form a thick batter. Keep aside for 30 minutes.
Just before steaming, add the eno fruit salt and combine well. Pour this batter onto a greased steel container and place inside a pressure cooker or steamer which already has some water in the bottom.
Steam without the vent (for the cooker) for 10 minutes on high flame and then 5 minutes on low flame. Set aside to cool for 5-10 minutes.
Demould onto a plate and cut into desired shapes. Heat oil in a pan and temper with the red chilly and mustard seeds.
After it stops spluttering, add the curry leaves and sesame seeds. Switch off the flame and saute till the sesame seeds changes colour.
Pour this tempering over the dhoklas and garnish with coconut and coriander leaves. It is ideal for a kids lunch box meal as it is healthy and steamed.
