Soak the Urad Dal in enough water for 2-3 hours or overnight.
Drain the water and grind the Urad dal along with jeera/cumin seeds to a smooth paste using no or very little water.
The batter should not be runny, we need a thick batter.
In a deep pan or a wok add the oil for frying.
Let the oil heat to medium heat.
In the meantime, incorporate air into the batter by mixing it vigorously with a hand or a spoon in a clockwise direction.
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. If you cook on high the outside will cook faster and the inside would not get cooked and would be raw.
They are done, when they are slightly golden brown all over.
Remove it in a colander or a kitchen towel.
Let them cool for 5-10 minutes.
