A good seasoning for a prime rib includes ground black pepper, salt, garlic powder, paprika, onion powder, seasoning salt and celery salt. The seasoning mix is rubbed into the prime rib and allowed to penetrate overnight.
To make this seasoning mix, combine 1/4 cup of ground black pepper, 1/4 cup of salt, 1/4 cup of garlic powder, 2 tablespoons of paprika, 1/4 cup of onion powder, 2 tablespoons meat tenderizer, 2 tablespoons of seasoning salt and 1 tablespoon of celery salt. Mix well and rub into prime rib, adding soy sauce to wet the seasoning. Use 2 cups of the seasoning for every 10 pounds of prime rib.
