Open the modak mold and grease it lightly with ghee.
Close the mold. From the hole at the bottom push in a some rice dough.
Using wet fingers press the dough to the sides of the mold.
Remove any excess dough that comes out. You should have a hole in the middle to fill it with the jaggery filling.
Take a tiny ball of filling and stuff it in by pressing it in through the hole.
Take a small piece of dough and flatten it into a small thin circle.
Cover the bottom with it.
Open the mold and remove the modak.
Gently press and shape the bottom part well. Press the modak gently on the surface to get a flattish bottom.
Place it on a greased tray.
Repeat with the remaining dough and filling.
