PREPARATION:
- Trim tops and roots from onions, leaving most of the dried outer skin intact; cut into wedges.
- Place onions, capon, carrots, celery, garlic, bay leaf, parsley, peppercorns, thyme and water into stockpot or 6-quart Dutch oven. Bring to a boil over high heat. Reduce heat to medium-low; simmer, uncovered, 3 to 4 hours, skimming foam that rises to the surface with large spoon.
- Remove broth from heat and cool slightly. Remove large bones. Strain broth through large sieve or colander lined with several layers of damp cheesecloth removing all bones and vegetables; discard bones and vegetables.
- Use immediately or refrigerate broth in tightly covered container up to 2 days or freeze broth in storage containers for several months.
