Take a bowl add gram flour, salt and add water slowly and gradually. We do this to avoid lumps. Put a steamer or kadhai add water and put a stand in the center. Add 2 cups of water. Once the water starts boiling take a thaali and grease it with oil. Add soda to the gram flour batter and pour this batter into the thaali. Put the thaali on the kadhai/steamer and cover it with lid.
