White Khatta Dhokla (Idada)

White khatta dhokla is a delicious fluffy savory snack from the Indian state of Gujarat. It is made from rice and black gram (urad) dal. It is soaked overnight, ground the next day and fermented for about 6-8 hours thereafter before steaming. The, "khatta," in the name describes the flavor of this dhokla. The sourness is bought about by adding a little sour yogurt. Although ready mixes are available to do the job quickly, they cannot match the taste of traditional khatta dhokla made with homemade batter. So here, I will tell you how to make dhokla using a batter of rice and urad. This recipe requires advance preparation.

5. Sprinkle red chilli powder on a batter. Steam in a steamer for 8-10 minutes until the dhoklas are cooked.
6. Repeat steps 4-5 to make more three more thalis. Note: If you have a four thali stand then use that to make it easier since you may make all four thali together.
7. In a small kadai, heat the oil and add mustard seeds. When they start to crackle, add hing and the slit green chili. Pour the mix on all four thalis of dhokla. Garnish with fresh coriander leaves.
8. Cool slightly and cut into square or diamond shaped equal pieces using a knife.
