After 15 minutes, whisk the batter for another minute.
Heat sufficient oil in a heavy-bottomed kadai on medium-high heat.
Add a drop of the batter to the oil to check if it has reached the right temperature.
If it sinks to the bottom the oil is not hot enough. If it rises to the surface immediately without changing color, the oil is ready.
Hold a slotted spoon (boondi jhara or grater) about 3 to 4 inches above the oil.
Pour a ladleful of the batter over the slotted spoon.
Drops of batter will fall into the hot oil and form a round shape. Once the boondi floats stir occasionally.
Deep-fry for about 40 seconds or until crispy. They should not turn golden brown.
Using another slotted spoon, drain the boondi and transfer them to a plate lined with a paper towel.
Repeat the same process with the rest of the batter.
Wash the slotted spoon under running water and wipe with a clean napkin/paper towel each time before proceeding with the next batch.
Make sure the ladle is completely dry to avoid hot oil from splattering all over and causing any mishaps.
