In a mixing bowl, add murmura and some water. Soak it for 5 minutes.
Remove the water with a sieve and press the murmura slightly to remove any excess water.
Add the murmura back to the mixing bowl and mash it with your hand.
Add cumin seeds, chopped green chilli, ginger paste, chopped curry leaves, salt, black pepper powder, coriander leaves, and rice flour. Mix well.
Gradually add curd to the mixture and bind it into a medium-soft dough. Do not knead the dough too much.
Grease your hands with oil and take a ball-sized piece of dough. Flatten it slightly and make a hole in the center.
Deep fry the vada in hot oil, keeping the flame on medium.
Fry the vada until it becomes golden brown and crispy on both sides.
Serve the murmura vada with coriander-coconut chutney.
