Preheat oven to 400 degrees. In a small bowl, combine chipotles, 1/4 cup honey, mustard powder, 3 tablespoons salt, and 2 teaspoons pepper.
Place a large double layer of foil on a large rimmed baking sheet. Place ribs on top and rub with chipotle mixture. Wrap ribs tightly in foil and bake on sheet until meat is fork-tender, 2 to 2 1/2 hours.
Heat grill to medium-high; clean and lightly oil hot grates. Remove ribs from foil, letting excess liquid drip off. Brush ribs with 1/4 cup honey and grill until lightly charred, 2 to 3 minutes per side. Cut between bones to separate ribs and serve with lemon wedges.
Cooking the ribs in foil means a quick cleanup. Be sure to wrap them tightly to hold in moisture and flavor.
