Ingredients

• 4 cups cold water
• 2 cups freshly brewed strong coffee
• 1 cup kosher salt
• 1/2 cup packed dark brown sugar
• 2 1/2 tablespoons Insta Cure No.1 (curing salt)
• 1/4 cup molasses (regular or robust, not blackstrap)
• 3 cups ice cubes
• 6 Pekin (sometimes called Long Island) duck breast halves with skin (about 7 oz each)
• Special equipment: a 1- to 2-gallon plastic storage tub; a 22 1/2-inch kettle grill with a lid and a hinged top rack; a 12- by 8- by 2-inch disposable aluminum roasting pan; 6 cups hardwood sawdust (3/4 lb; not from treated wood; see Shopping List, page 162); charcoal briquettes; a chimney starter; long metal tongs; an instant-read thermometer

Instructions

1. Stir together water, coffee, kosher salt, brown sugar, and Insta Cure in storage tub until solids are dissolved, about 3 minutes, then add molasses and stir until dissolved. Add ice and stir until cure is cold (ice may not melt completely; keeping liquid cold slows salt absorption).
2. Add duck to cure and weight down with a large plate (to keep submerged). Chill, tub covered with a lid or plastic wrap, 6 hours.
3. Rinse duck and pat dry, then discard brine.
