Blackening Spice Rub for Pork Ribs

About Blackening Spice Rub

Blackening Spice rub delivers a intense, spicy, Cajun-inspired flavour profile that pairs brilliantly with pork ribs. Made famous by Chef Paul Prudhomme. The triple-pepper blend (cayenne, black, white) creates layers of heat. Cook on screaming-hot cast iron for authentic blackening.

Ingredients

Makes enough for approximately 2 racks of ribs.

How to Apply Blackening Spice Rub to Pork Ribs

1. Mix the rub: Combine all dry ingredients in a bowl. Break up any brown sugar clumps with a fork.
2. Prep the pork ribs: Pat the meat completely dry with paper towel. Remove the membrane from the back of the rack — grip it with a paper towel and pull firmly.
3. Apply a binder: Lightly coat the pork ribs with yellow mustard or olive oil. This helps the rub stick — you won't taste the mustard after cooking.
4. Apply the rub: Generously coat all surfaces with the rub, pressing it into the meat. Don't be shy — a thick, even layer creates the best bark.
5. Rest: Let the rubbed meat sit for 1-12 hours (overnight is best) in the fridge (uncovered for better bark formation).
6. Cook: BBQ at 110-135°C (225-275°F) using low and slow, 3-2-1 method until the internal temperature reaches 91-96°C (195-205°F) probe tender.

Tips for the Best Results

• Pat the meat dry — moisture is the enemy of a good bark. Dry surfaces create better crust.
• Don't rush the rest — letting the rub sit on the meat allows the salt to penetrate and the spices to bloom.
• Apply generously — a thin dusting won't cut it. You want a visible, even layer across the entire surface.
• Store extra rub — this mix keeps in an airtight container for up to 3 months. Make a double batch.

Common Mistakes to Avoid

• Wet meat surface — if the meat isn't dry, the rub won't adhere and you'll get a soggy crust instead of a bark.
• Too much sugar on high heat — if combining with a sugary glaze, apply it late in the cook to prevent burning.
• Skipping the binder — mustard or oil helps the rub stick. Without it, half your seasoning falls off on the grill.
• Not enough rub — err on the side of generous. The flavour concentrates as moisture evaporates during cooking.

Best Cooking Methods for Blackening Spice Pork Ribs

Cook your blackening spice-rubbed pork ribs using low and slow, 3-2-1 method at 110-135°C (225-275°F).

The 3-2-1 method works brilliantly: 3 hours unwrapped in smoke, 2 hours wrapped in foil with a splash of liquid, 1 hour unwrapped to set the bark.

Target internal temperature: 91-96°C (195-205°F) probe tender.
