Get you steaming device ready. I use a pan which has a steamer and lid.
Add water to the bottom pan. It should not touch the steamer basket or plate.
Allow it water to come to a boil.
In the meantime lightly grease a steel plate which is 8-9 inches in diameter.
Place it on the steamer basket or plate. Allow the plate to become hot along with the water at the bottom.
Once the water is boiling, add Eno or baking soda to the batter.
Give it a quick but brief whisk. Don't over mix as you will loose the fluffiness.
Pour the batter in the hot steel plate.
Sprinkle some red chilli powder or black pepper coarsely ground on top.
Cover the lid.
Allow the dhokla to steam for 10 minutes.
Insert a toothpick or fork in the middle of the steamed dhokla.
If it is done, the toothpick or fork will come out clean.
Remove the dhokla from the steamer.
