  • Double the sauce for the recipe and serve it on the side in a sauce dish or gravy boat.
  • This recipe is excellent with boneless country-style ribs as well.

Recipe Variations

  • A boneless pork shoulder can be used instead of the leaner pork loin roast. If you do use a pork shoulder, add at least 2 hours or more to the cooking time. It should be very tender.
  • Replace the barbecue sauce ingredients with about 2/3 cup to 1 cup of your family's favorite commercial sauce.
  • Add a small amount of liquid smoke or mesquite seasoning to the sauce for a smoky flavor.
  • Add about 1/4 to 1/2 teaspoon of crushed red pepper flakes to the sauce mixture.
