Soak the rice and urad dal separately in water for 6–8 hours.
Drain the soaked ingredients and blend them together with plant-based curd and water to form a smooth batter.
Add salt to the batter and mix well.
Allow the batter to ferment for 6–8 hours in a warm place.
Heat a non-stick pan and grease it lightly with oil.
Pour a ladleful of batter onto the pan and spread it in a circular motion.
Cook until the edges lift and the bottom is golden brown.
Flip and cook the other side for a minute.
Repeat with the remaining batter.
Serve hot with chutney or sambar.
