1. Rinse the rice and urad dal separately until the water runs clear.
2. Soak the rice and fenugreek seeds together in water for at least 4 hours. Soak the urad dal separately for the same amount of time.
3. Drain the soaked rice and dal. Grind the urad dal to a smooth paste, adding water as needed. Grind the rice and fenugreek seeds to a slightly coarse paste. Mix both pastes together in a large bowl.
4. Add salt to the batter and mix well. Cover and let it ferment overnight or for about 8-12 hours.
5. Once fermented, stir the batter. Heat a non-stick pan over medium heat. Pour a ladleful of batter onto the pan and spread it in a circular motion to form a thin crepe.
6. Drizzle a few drops of oil around the edges. Cook until the edges start to lift and the bottom turns golden brown. Flip and cook the other side for a minute.
