Remove the membrane from the back each rack of baby back ribs using a knife to get it started in one corner, then grabbing on with a paper towel and pulling towards the opposite corner.
2 Racks Baby Back Ribs
Apply a thin layer of yellow mustard to the front and backs of each rack of ribs and rub to coat entirely.
2 tablespoon Yellow Mustard
Use your favorite BBQ rub or mix the rub ingredients listed above together in a bowl or shaker.
1 cup Your Favorite BBQ Sauce, 1 cup Dark Brown Sugar, ½ cup Paprika, 2 tablespoon Course Ground Black Pepper, 2 tablespoon Kosher Salt, 2 tablespoon Chili Powder, 1 tablespoon Granulated Garlic, 1 tablespoon Onion Powder, ½ teaspoon Cayenne Powder
Apply a generous amount of rub to the fronts and backs of each slab of baby back ribs. Its ok to leave some rub leftover to apply more throughout the cook if needed.
Let the rub set on the ribs at room temperature for about 20-30 minutes. This is a good time to start up your Pit Boss (see next section)
While the rub is setting and the Pit Boss is preheating, you can also mix the apple juice and apple cider vinegar together in a spray bottle for spritzing later.
