To make batter, mix all the dry ingredients together, all-purpose flour, rice flour, salt, baking soda, and cumin seeds. Add yogurt mix it well add the water to make thick batter.
Heat 200 ml of oil in medium heat. The frying pan should have about 1 inch of oil. To check if the oil is ready, put little batter in oil. The batter should sizzle and come up but not change color right away. If oil is very hot bondas will not cook thoroughly and will not be crispy.
Place about 2 tablespoon of batter into the oil with your fingers. Fry bondas in small batches.
Fry them until golden-brown all around. This should take about 3-4 minutes.
