By the time we are making chutneys and curd, dal got enough time to soak. Drain the water.
Transfer dal in a grinder jar.
Also add green chilli, ginger and salt.
Start grinding.
Keep checking and add little water at a time until you get smooth and flowing consistency of batter.
Transfer the batter in a wide bowl.
Add cumin seeds.
Start beating the batter with electric beater.
Note : if you don't have electric beater, simply use hand whisk or even hand itself can be used, though that will be slightly time taking.
After 5-6 minutes of beating, batter will turn fluffy as the air has incorporated in it.
Go for a test to check whether batter is enough beaten or not, drop a dollop of batter in bowl carrying water.
If batter floats over the surface of water, it's a sign that batter is perfectly whisked. If batter drops in water, you need to beat the batter for some more time.
