Ingredients

5 pounds chicken bones 

1 large onion, peeled and quartered 

1 large carrot, cut into thirds 

2 celery stalks, cut into thirds 

2 large or 4 small leeks, cut in half lengthwise and well washed 

2 bay leaves 

6 sprigs of fresh flat-leaf parsley 

1/2 teaspoon dried thyme 

12 whole black peppercorns 

Preparation

Place all the ingredients in an 8-quart stock pot and cover with cold water. Bring to a boil over high heat.

As the stock approaches a boil, remove any impurities that rise to the top by skimming with a ladle. Reduce the heat and simmer the stock for 3 to 4 hours, continuing to skim impurities from time to time while the stock cooks. Taste after 3 hours for the strength of stock you want.

Remove from the heat and let the stock sit for 10 to 15 minutes, then ladle through a fine strainer. Once strained, remove the fat from the stock by skimming with a ladle (see Helpful Hint). Cool by placing the container of strained stock in an ice water bath, then refrigerate.
