Chicken stock

Besides cooking with stock, I like making it-- there's something homey about a pot simmering on the stove for hours.

3 lbs chicken carcasses, 2 good sized onions, chopped up Chinese celery, and a few garlic cloves. I skimmed fat a few times and filtered it for schmalz. The pot yielded ~3 quarts-- I'll freeze pints in ziplocs tomorrow and fill an ice cube tray.
