Whisk together all ingredients in a medium bowl. Store in an airtight container for up to a year.
To use, sprinkle directly on shrimp or combine with olive oil to make a wet rub. Toss to coat shrimp and cook on the grill or sautee in a pan.
Notes
Slap Ya Mama white pepper seasoning is a tad spicier than the original. It uses white pepper in place of black pepper which gives it a slightly different taste. You can easily substitute with homemade Cajun seasoning or the original Slap Ya Mama seasoning.
