Take a bowl and add all the ingredients, except Eno fruit salt, as mentioned under Dhokla ingredients.
Take a wire whisk and mix well into a smooth batter. It is a thick batter.
Cover and Set the batter aside for 12-15 minutes for resting.
Now take the idli or Dhokla steamer or a big pressure cooker or a deep pot with lid.
Set the steamer stand in the middle of the cooker/steamer. Fill the pan with water till the top of the steamer stand. Bring the water in the steamer to a boil.
Meanwhile grease a Dhokla plate or a 7 inch wide steel contained (katordaan) with oil. Grease the sides also.
Now add 1 tsp Eno fruit salt to the Dhokla batter. Whisk quickly and pour the batter into the greased container.
Set the batter container on the steamer stand inside the pot.
Cover with pot/cooker/steamer with its lid. If using pressure cooker, do not use the weight on top of it.
Steam the batter on high for 2 minutes and then steam for another 13 minutes on medium. Steam for total 15 minutes. Switch off the gas stove. Once the steam escapes, open the lid. Take out the container and Let the Dhokla sit there. Meanwhile, work on the tempering.
