1 (24 ounce) bottle ketchup
1 cup granulated sugar (1/2 cup may be enough)
2 tablespoons Worcestershire sauce
2 teaspoons chili powder
1 medium onion, chopped
1/4 to 1/2 teaspoon garlic salt
1/2 cup tarragon vinegar
This recipe came with no instructions. This is what I have worked out. Blend the onion with the other ingredients in a blender, then warm the sauce. For ribs or chicken, bake as usual, and then add the sauce for 10 minutes as it burns easily.
