Ok - Donna gave me permission to post the details of my variation on their recipe so here goes. By the way, the Cookshack BBQ sauce mix is available by calling Cookshack at 1-800-423-0698. And lest I get flamed, the liquid smoke was part of their original recipe.
Steve's Barbeque Sauce
======================
1 1/3 cups dark brown sugar
2 tablespoons Cookshack BBQ sauce mix
3 1/2 teaspoons salt
1 teaspoon powdered garlic
1 teaspoon cinnamon
1 teaspoon dry mustard
1/2 teaspoon ground coriander
1/2 teaspoon cayanne pepper
1/4 teaspoon cloves
1/8 teaspoon nutmeg
2 1/2 cups water
2 cups tomato paste (a little less than 2 x 12-ounce cans)
2 cups white vinegar
5 ounces unsulphered blackstrap molassas
5 ounces tomato sauce
5 tablespoons Worcestershire sauce
3 tablespoons liquid hickory smoke
5 teaspoons Louisianna hot sauce
Combine all ingredients and whisk over high heat until almost boiling. Simmer
10 minutes. Pour into pre-heated Mason jars, seal with new lids, and process in boiling water for 10 to 15 minutes. (The water must be boiling vigorously for the whole 10 to 15 minutes). Let the jars cool on the counter. Once the jars are cool, check the lids to make sure they are all "sucked down". You do this by pressing on the center of the lid. If it doesn't move when you press on it, that is ok. If it pops down when you press on it, then there is no vacuum in the jar and that is bad.
If any jars will not hold a vacuum, then you may have a chipped jar or a defective lid. This is a pretty rare thing, but it can happen. All I do is put that jar in the refrigerator, and use it next. Or, you can change the lid and/or jar and reprocess it in boiling water. Don't worry about it, just don't store anything at room temperature if it is not properly sealed.
This sauce is pretty acidic, so it doesn't spoil very easily, thus it is one of the easiest things to "can." Low-acid foods require a different (pressure) canning process, and/or longer processing times.
