I always thought that a Texas rub was basically salt and black pepper. I did a brisket with this rub and wasn't impressed. My Go to rub is from the book "Smoke and Spice", and is called Wild Willy's Number One-derful ( Wild Willy’s Number One-derful Rub | Cookstr.com ). I also ran across a recipe for a salt, pepper, garlic, and onion rub that we really like:
Seasoning Mixture - Salt, Pepper, Garlic, & Onion
Ingredients
3 Tbsp Kosher Salt
1 Tbsp & 1 Tsp Black Pepper
2 Tsp Granulated Garlic
1 Tsp Granulated Onion
Directions
Add all ingredient to an air tight container (Tupperware works well) and shake vigorously. This spice will keep up to a month in a dry place.
The thing I like about mixing my own rubs is the ability to change them to suit what we like. With the SPGO rub, we like pepper so I mix it 3 Tbsp of pepper.
