Cook time: 5–6 hours at 225°F

Cooking tip: Remove the membrane from the bone side before rubbing. Cook at 225°F and check tenderness by bending the rack: it should crack on the surface when ready.

Food safety: don't leave cooked meat out more than 2 hours, or 1 hour above 90°F (USDA). Keep hot food above 140°F.
