Below is a recipe from The Second Ave Deli Cookbook for gribenes, a dish popular during Chanucah. It is a dish comprised of fried scraps of fowl (the name literally means "scraps") and is served with potatoe pancakes or rye bread. It is a wonderfully thrifty way to use up leftover chicken.
Gribenes
4 cups chicken fat and skin, cut into 1/2-inch pieces or smaller
Kosher salt
Pinch of pepper
1 cup onion rings, about 1/8-inch thick
Wash fat and skin well in a colander, and pat dry. Place in a heavy skillet, and sprinkle lightly with salt and pepper. Cook, uncovered, over low heat (you can turn it up a bit once the fat has begun melting). When the fat starts to melt and get slightly brown, add onions (and garlic cloves if you like), and continue cooking until onions and cracklings are golden brown and crunchy. When partially cooled, strain over a bowl to remove onions and cracklings, and refrigerate them in a covered glass jar. Poor schmaltz into another jar, cover, and refrigerate.
