Step by step
Tap a step to cross it offMembrane Removal & Seasoning
Use a paper towel to grip and peel the white papery membrane off the bone side of 2 racks of St. Louis ribs. Coat both sides with yellow mustard binder, then season generously with sweet pork dry rub.
WhyRemoving the membrane allows wood smoke and rub to penetrate the bone side directly.
The 3-Hour Smoke (Bark Formation)
180 minPlace ribs bone-side down directly on smoker grates at 225°F. Smoke undisturbed for 3 hours.
WhyDo not open the smoker lid during the first 3 hours to ensure maximum smoke adherence and bark development.
The 2-Hour Foil Wrap (Tenderize)
120 minTransfer each rack onto a double layer of heavy-duty foil. Top with 3 tbsp butter, 2 tbsp brown sugar, and 2 tbsp apple juice. Wrap tightly and return to smoker for 2 hours at 225°F.
WhyThe foil wrap creates an aromatic braising chamber that breaks down tough collagen into succulent juice.
The 30-Minute Glaze Set & Rest
30 minCarefully unwrap ribs and place back on grates. Brush with barbecue sauce. Smoke for 30 to 45 minutes until glaze is sticky and meat bends 90 degrees when picked up with tongs (internal temp 202°F). Rest 15 minutes before carving between bones.
WhyResting allows juices to settle into the meat fibers so ribs slice cleanly without shredding.
