Ingredients

5 to 6 pounds chicken backs, necks, and wings (or one 5- to 6-pound chicken) 

2 stalks celery, cut into 2-inch lengths 

3 medium carrots, cut into 2-inch lengths 

2 medium onions, coarsely chopped 

4 sprigs fresh thyme 

4 sprigs fresh parsley 

1 teaspoon whole black peppercorns 

2 dried bay leaves 

Preparation

In a large stockpot, combine all ingredients. Add enough water to cover by 2 inches (about 20 cups). Bring to a boil. Reduce to a simmer, and cook for 3 hours.

Prepare an ice bath. Strain stock through a fine sieve into a large bowl set in the ice bath. Let stand, stirring occasionally, until room temperature. Transfer to airtight containers.
