Memphis Dry Rub Ribs

Ingredients

• 2 racks pork spare ribs, St. Louis cut, rib tips trimmed to a uniform rectangle, membrane removed from bone side
• For the dry rub
• 60 g paprika, sweet, not smoked — this is the rub's base colour and sweetness
• 20 g black pepper, coarsely ground
• 15 g garlic powder
• 15 g onion powder
• 10 g celery salt
• 10 g cumin, ground
• 10 g dry mustard
• 10 g brown sugar, light; one element among many — not the dominant note
• 5 g cayenne, adjust to heat preference
• For the smoke
• 2 kg charcoal, hardwood lump preferred
• 4–6 hickory wood chunks, fist-sized; soaked 30 minutes if using chips

Method

1. 1
   Combine all rub ingredients and mix thoroughly. Pat the ribs dry. Apply the rub to every surface — top, underside, and edges — pressing firmly so no bare meat is visible and no individual grains remain proud. The rack should appear uniformly dark-red and densely coated. Rest uncovered at room temperature for 30–60 minutes, or refrigerate overnight. The surface will turn slightly tacky as the rub draws moisture: this is correct.
2. 2
   Prepare the smoker for indirect heat. Establish a steady temperature of 110–125°C at grate level. Add two or three hickory chunks to the coals. The smoke issuing from the vent should be thin and blue-white, not grey or billowing — acrid, heavy smoke will overpower the rub rather than complement it. Maintain this smoke character throughout.
3. 3
   Place the racks bone-side down over indirect heat. Close the lid. Do not sauce, baste, or wrap. Maintain 110–125°C for 4–6 hours, replenishing charcoal and one or two hickory chunks as needed to hold temperature and a consistent thin smoke. At the 4-hour mark, begin assessing. The bark should be deeply set, dark, and dry to the touch — this is where the dish lives or dies: if the rub has formed a firm, caramelised crust across every surface, the bark that is the rib's entire flavour and texture architecture has been built; if it is soft, tacky, or pale, the ribs need more time at temperature, and no subsequent step will recover what was lost.
4. 4
   Apply the pull test. Grip the exposed end of a bone and rotate it gently. A done rib allows the bone to turn and pull cleanly from the meat with moderate resistance. Meat that falls away at a touch is overcooked; a bone that does not move at all requires more time. The correct result is unambiguous: the bone rotates freely, the meat releases cleanly, and the rack holds its structure without sagging.
5. 5
   Additionally confirm by sight: the meat should have pulled back from the bone tips by approximately 1 cm, exposing clean bone. The bark surface should be uniformly dark and rigid — not charred black, not glossy with rendered fat. Rest the racks, uncovered and on butcher paper, for 10 minutes before cutting between the bones.
