Take Urad dal and soak it into the water for 5-6 minutes. Now put it in the grinder, grind with little water and make thick and smooth paste (should not be use too much water). Dal paste should be thick and fluffy. Now add fresh chopped coconut, curry leaves, chopped green chilli, cumin powder (don’t use roast one), chopped ginger, chopped coriander, mix it well and whip for 2-3 minutes or batter becomes fluffy. Once fluffy, add salt & mix again.
