Combine all spices in a bowl and mix very well. (You can also combine it in a jar with a lid, close the lid and shake well to mix.)
Storing:
Keep the dry rub in an air-tight glass jar. Make sure to keep it in a cool, dark, place away from direct sun, direct heat, and moisture. Stored properly, dry rubs should be good for up to 6 months.
To Freeze:
For the best way to keep dry rubs fresh, store it in the freezer. Use a zip-top freezer bag, get as much air out as you can, seal, and label the bag. Store it for up to 8 months in the freezer.
