It's just a basic beer mop that I took from Smoke and Spice and changed a bit. BBQBob named it Rick's Sinful Marinade. Here it is;
Rick's Sinful Marinade
12 oz. can of beer
½ cup cider vinegar
½ cup of water
¼ cup olive oil
¼ cup Worcestershire sauce
2 tablespoons barbeque sauce
1 tablespoon seasoned salt or rub.
1 tablespoon celery seed
1 teaspoon cayenne pepper
Mix the ingredients and baste as necessary, or add when wrapping at about 165*.
