Grease a steamer pan with little tsp oil.
Take 2 to 3 cups of water in a steamer pan or pressure cooker and allow it to boil
Mix together all the ingredients for the batter except the fruit salt(eno).
Stir to a smooth thick batter without any lumps.,Use enough water to make a easy pour consistency batter.
Add in the Eno or fruit salt to the dhokla batter. Mix well
The batter would froth and become bubbly, so you have to be quick.
When the mixture rises, pour it into a steamer pan or greased thali and steam for about 15 minutes.
To check if it is ready, insert a toothpick and if it comes out clean, the dhokla is done. If the toothpick has the batter on it ,then you need to steam for some more time.
Once done allow the Khaman to cool down for 20-25 mins. Take it out in a plate. Cut it in small pieces.
