Add 3 Tablespoon Brown Spicy Mustard, 2 Tablespoons Ground Coffee, 2 Tablespoons Paprika, 2 Tablespoons Granulated Garlic, 2 Tablespoons Minced Onion, 1 Tablespoon Brown Sugar, 1 Tablespoon Black Pepper, and 1 Tablespoon Salt to a bowl.
Mix together. Use immediately or store in the refrigerator (unless excluding the spicy brown mustard).
Notes
The two key ingredients to making coffee rub are the ground coffee and the brown spicy mustard. The brown spicy mustard is applied first, before the coffee rub, by rubbing it on the meat. If you prefer, it can be left out entirely and only the coffee dry rub may be used.
Store leftover coffee rub, without the mustard, in a tightly sealed jar for up to a month.
