Put grated coconut, cumin, coriander seeds, red chillies and curry leaves in a mixer and grind to make fine paste. Don't add any water to grind.
Next transfer the ground paste to a wide bowl. Add rava, wheat flour and salt to this. Combine everything well. Add water in steps, little by little and make pliable dough. I used up almost 1/2 cup water.
Cover the dough with a damp cloth for about 10 minutes. Next add 4 tsp of hot oil to the dough and knead once again.
Next pinch lemon sized dough and roll between your palms to shape like a rope. Join both ends together to form a ring. Repeat this process with rest of the dough. Heat enough oil in a wok and deep fry the ring murukku in batches. When they turn little brown remove from oil and drain.
Shree Krishna Janmashtami special rava ring murukku is ready.
