Ingredients

1 leek sheath 

2 sprigs fresh flat-leaf parsley 

1 sprig fresh thyme 

2 bay leaves 

1 chicken carcass, chopped into 4 pieces, rinsed and patted dry 

1 yellow onion, diced 

4 ribs celery, cut into 1-inch-long pieces 

2 large tomatoes, chopped 

4 black peppercorns 

Preparation

Tie together leek, parsley, thyme, and bay leaves with a piece of kitchen twine; set herbs aside.

Place chicken carcass in a large stockpot along with onion, celery, tomatoes, tied herbs, and peppercorns. Add enough cold water to cover carcass by 2 inches.

Bring to a boil and immediately reduce to a simmer over low heat. Cook, skimming top as necessary, 2 hours. Strain and discard solids. Let stock come to room temperature before storing in covered containers.
