In a large mixing bowl, add yoghurt and 2 tbsp of water and whisk it nicely to avoid any lumps.
Add more water if needed to make the yoghurt in pouring consistency.
Add rava into the whisked yoghurt and mix it nicely.
Adjust the water if the mixture is dry.
Add salt, sugar (optional, I do not use sugar), grated ginger, green chilli and mix it nicely.
Now, cover the batter and keep aside for 14 to 15 mins.
After 15mins, add Eno fruit salt and mix it immediately and transfer the batter to the greased pan or plate.
Steam the prepared mixture for about 12 minutes on medium-high flame.
Now, remove the dhokla and cut into 1-inch pieces.
