Marinate the cubed liver with the above mixture for atleast 1/2 hour.

Heat ghee in a pan or a kadai.

Fry onions, till golden brown.

Add chopped tomato and fry, till pulpy.

Add the marinated liver chops.

Add little water (about 1/2 cup).

:- Remember to use as little water as possible, since excess water would cause the liver chops to harden.
