Wash and Soak the Urad Dal in enough water for 1-2 hours.
Drain the water and grind the Urad dal along with jeera/cumin seeds to a smooth paste using no or very little water.
In a deep pan or a wok add in the oil for frying.
Let the oil heat to medium hot.
In the meantime, incorporate air into the batter by mixing it vigorously with hand or a spoon.
Drop a little batter in water, if it floats your batter is ready.
Once the oil is hot, take about a tablespoon of batter in your fingers.
Gently slide this in hot oil.
Let this cook on medium to slow heat turning in between.
Do not cook on high, we do not want the outside to cook faster and the inside raw.
Once cooked soak them in room temperature water for 20-30 minutes.
