Mustard Rib Rub

Mustard Rib Rub is a spice mixture combined with Dijon mustard, used to coat baby back ribs before slow baking. The rub includes aromatics like garlic and onion powders, cumin, oregano, smoked hot paprika, and brown sugar, creating a balanced flavor with savory, smoky, and sweet notes. Baking low and slow yields tender ribs that can be paired with traditional sides.
