8 oz. unrendered chicken fat & skin
1/2 med. onion, coarsely chopped

Place fat and skin along with chopped onion in a clear quart microwave container (such as a Pyrex measuring "cup"). Place in microwave oven and cover loosely (with a glass cover, plate or wax paper). Cook on high until fat is liquid and skin pieces (grebenes) are brown and crisp, around 6-8 minutes. Saves grebenes, after draining, for use in kugels, stuffing, etc. Strain the liquid fat and discard the onion pieces. Pour fat into jar, cover and refrigerate or save in freezer.
