In a large saucepan, over medium heat, mix together all the wet ingredients and then add the seasonings.
Bring to a boil then reduce the heat to low and simmer for at least 20 minutes or up to an hour, stirring occasionally. The sauce will thicken slightly as it cools.
Once cooled, the sauce can be frozen. Thaw in the refrigerator and use as needed.
Notes
Spices: I've found over the years that I like to reduce the celery seed to 1/4 teaspoon (I've left the amount as the original 1/2 teaspoon) and also decrease the coarse, ground black pepper to 1/2 teaspoon since it packs a little heat. The spices and flavorings in this recipe are adaptable like that! Try using smoked paprika in place of regular paprika for extra deliciousness!Freezable: This BBQ sauce freezes great!
