Most commercial spice rubs contain more salt than any other ingredient, per the content label, so I make my own with Aleppo pepper, ground garlic, smoked salt, cumin, ground onion and, occasionally, chili powder, paprika, and/or mustard powder. I use Aleppo pepper because it has milder heat (than cayenne) and wonderful fragrance and flavor. You can adjust the amounts to suit your taste. NY Spice Shop provides this pepper at a very reasonable price.
