Drain out the excess water from the Urad Dal.
Grind it into a fine paste. If you find it difficult to make a fine paste without adding extra water, add water spoon by spoon. Use as little water as possible.
Transfer this paste to a big mixing bowl.
Add ginger, coriander, curry leaves, black pepper, cumin seeds and salt.
Mix well. Now, with your hand beat this mixture well for about 5-7 minutes, till it becomes light and foamy.
To test whether the batter is ready, take a bowl of water. Put a small portion of the whisked batter on it. If it floats, the batter is ready.
Heat oil in a pan.
Take portions of the batter and drop them into medium-hot oil.
Fry them till they are golden brown.
Remove them on a paper towel and let them cool.
