Ingredients

1 1/2 pounds lamb bones 

1 medium-size onion, peeled and pierced with 1 whole clove 

1 carrot, peeled 

1/2 cup fresh celery leaves 

1/2 cup parsley stems 

1 garlic clove, peeled 

1 teaspoon kosher salt 

8 whole black peppercorns 

1 fresh thyme sprig 

Preparation

In a stockpot, combine the lamb bones with about 12 cups of cold water, or enough to cover.

Bring the mixture to a boil and skim off the froth. Add the remaining ingredients and simmer over low heat, covered partially, for 2 hours. Strain the broth through a sieve, discarding the bones and the vegetables.

Allow the stock to cool. Chill the stock in the refrigerator and skim off the fat.
