To store, spoon 1-tablespoon portions of cooled Glace into an ice-cube tray. Cover with plastic wrap; freeze. Place cubes in a container; freeze up to three months.

1. Preheat oven to 425°.
2. Place chicken in a broiler pan or shallow roasting pan coated with cooking spray. Bake at 425° for 1 hour, turning thighs after 30 minutes.

Add remaining 10 cups cold water; bring to a boil. Reduce heat, and simmer 2 hours; skim surface occasionally, discarding foam.
4. Strain stock through a fine sieve lined with cheesecloth or a thin cotton dish towel into a large bowl; discard solids. Cool stock to room temperature. Cover and chill stock for 8 hours or overnight.
