Grease a flat bottom vessel with oil. you can use dhokla patra (i used the cheesecake spring foam pan)

In a separate bowl mix all the ingredients with enough water to make a thick batter.

Pour the batter into the greased pan, steam cook for 30 minutes in a pressure cooker without the whistle. insert a toothpick or a knife, if it comes out clean the kothimbir vadi is done. Keep aside to cool unmould and cut into pieces.

Before serving, heat oil in a pan & shallow fry the vadis on medium heat till crisp & they change their color to brown.

Serve hot with a tomato ketchup.
