The liver in the form of frozen cut into pieces with a thickness of 1-2 cm. Liberally sprinkle baking soda. Mix well. Let it stay like that for at least 4 hours.

After that, the liver thoroughly washed, season with salt and pepper and fry in a skillet in very hot vegetable oil without smell. Fry 1.5 minutes on each side, so she grabbed. Put in the pot (in my case in a clay pot), pour each layer with finely chopped onions and sour cream. And simmer 30 minutes.

It turns out very tasty, soda is not felt.
