To make curd vada, wash and soak urad and moong dal without skin for 3/4 hours. After four hours, grind the dal to a fine powder. Then grind it. To check whether the dal is ready for vada, put a little batter in a bowl filled with water. If the batter stays on top of the water, then the batter is ready

Then the batter is ready for vada. Now heat the oil and put the vada in your hands. Then reduce the heat a little and fry it until crispy. Then soak it in buttermilk for 5 minutes. Mix sugar, salt and a little chaat masala in the cold curd. Place the vada in a dish. Then add the curd and garnish with red chilli powder, chaat masala and coriander. Cool it in the fridge for a while and serve.
