Heat oil in a deep pan or kadai.
Check if the oil is hot by dropping a small piece of ball to the hot oil. The ball must go in and rise slowly with bubbles. This is the right time to fry the balls.
Regulate the flame to medium. Begin to drop one ball at a time. Slowly add as many balls as possible. Keep stirring the oil to fry them evenly.
After frying for few minutes they will firm up. Keep stirring and fry them uniformly until golden brown. If needed regulate the flame to low and medium often.
Remove the balls that are done to a kitchen tissue. Continue frying and removing when ever a ball is done frying.
