Dump the sauce, go with a rub.
IMHO, the main purpose of a sauce is to cover up the taste of a poor cut of meat. Oh, you're buying good cuts of meat? Then why cover it up with a sauce?
It has been my experience that rubs tend to bring out and work with the flavor of the meat, not cover it up.
Here are a couple of rub recipes:
Memphis style rib rub:
1/4 cup paprika
2 tablespoons salt
2 tablespoons onion powder
2 tablespoons fresh ground black pepper
1 tablespoon cayenne
Mix ingredients together. Store in an airtight container. Spread evenly on prepared ribs that have been patted dry and let sit until the rub appears moist.
Best odds rib rub:
1/3 cup paprika
3 tablespoons dry mustard
3 tablespoons onion powder
3 tablespoons garlic powder
2 tablespoons ground basil
1 tablespoon black pepper
1 tablespoon salt
2 teaspoons red pepper (1 tablespoon if you want it hot)
Combine all ingredients. Store in an airtight container. When applying to ribs, coat heavily and massage into the meat. If you want to make a sweet rub add 2 tablespoons of brown sugar (obviously not paleo).
There is a whole world of BBQ out there that doesn't use sauces. Why not try something new?
