Mix the chili powder and paprika together in a bowl for easy handling. After that, mix in the garlic powder until it is completely incorporated.
Add the black pepper, salt, and onion powder one at a time while the mixture is being mixed.
After adding the cayenne pepper, whisk for another two minutes to ensure that all of the spices are thoroughly combined.
You may also put all of the spices in a bag with a zip-top and shake the bag for a few minutes to blend them.
After that, you can use Jeff's smoked beef rub recipe, which is a particular handcrafted recipe. It keeps well either in the fridge or on the counter.
