Chopped Chicken Liver a la Jennie Grossinger
How to render chicken fat: Remove fat and the fatty skin from chicken. For each cup of fat to be rendered, you need 1/4 cup sliced onions and 1 slice apple. (I usually only use onions). Wash and drain the fat and cut into small pieces. Cook over low heat until the fat is almost melted. Add the onions and apple and cook until the onions brown. Cool and strain. The onions and pieces of skin (gribenes or cracklings) can be used for other things.
