Mix the dry rub. Combine the fine sea salt, smoked paprika, black pepper, garlic powder, onion powder, ground mustard powder, and cayenne pepper in a small bowl, then mix until you have an even blend. I recommend using a whisk or fork so you can break up any clumps.
Use immediately or store for later. Use your dry rub right away on your favorite smoked or grilled wings, or place it in a seasoning jar and store in a dry place to use for up to 6 months. Your rub will still be safe after that, but you may want to make a new batch for fresh flavor.
