For making the kozhukkattai:
1)Spread oil on your left palm.
Take a small quantity of the kneaded dough and make it into a lime-sized ball.
Dip your right forefinger in oil and shape the dough into a nice cup with your right finger making the sunken portion of the cup.
Keep some filling into the cup.
Seal the top nicely with the sides of the cup. It should look like an onion bulb.
