Latvian Pate - cooking recipe

Ingredients

1 lb chicken liver, fresh
1/2 lb butter
1/2 onion, scraped (I have no idea what that means, so I whirl in food processor as small as possible)

1 pinch ground cloves
1 dash cayenne
salt
pepper

Preparation

Saute livers in 1/4 lb of the butter until done.
Whirl in food processor (recipe said food mill, I updated).
Add remaining butter, onions and spices. Blend well.
Place in mold and freeze until needed.
