Pressure Cooker Chicken Stock (using a whole chicken)

The pressure cooker produces a full-bodied stock in one-third the usual time because it quickly draws the gelatin out of the bones!

1 whole chicken
4 cups water
1 large onion, quartered (no need to peel)
a few leek greens (optional)
1 carrot, cut into chunks
1 rib celery, cut into chunks
2 large bay leaves
¼ tsp whole black peppercorns
1 small handful fresh parsley

Set a whole chicken in the pressure cooker, breast side up with 2 cups water and remaining ingredients, with the exception of the parsley. Cook for 20 minutes on high pressure. Allow pressure to come down naturally. Remove chicken, carve off meat, and reserve for another use. Return bones to the cooker, add parsley and 2 additional cups of water. Cook for an additional 20 minutes on high pressure.

Allow broth to cool. Strain into a storage container, pressing the solids to release all the liquid into the container. Chill; then remove congealed fat. Refrigerate and use within 4 days or freeze for up to 4 months.

Makes 4 cups cooked chicken and 1 quart of stock.
