Measure out the following spices: salt, black pepper, paprika, rosemary, garlic powder, onion powder, and cayenne.
Add all the spices into a small bowl and mix until thoroughly combined.
Rub all over a tri-tip roast, pork ribs, or seafood, and smoke or grill.
If not using the Santa Maria Seasoning right away, store it in an airtight jar for later use.
Notes
If storing the Santa Maria Seasoning for later use, leave out the fresh rosemary and add it just prior to using it.
If you own a mortar and pestle (affiliate link), you can use it to grind the rosemary into the other seasonings.
I don't recommend storing this seasoning longer than 3 months. As a matter of fact, I prefer making a fresh batch each time I make my Santa Maria Tri-tip recipe.
