Add the sweetener, vinegar, and water to a medium sized sauce pan, over medium heat. Stir and dissolve the sweetener.
Add all of the remaining ingredients to the sauce pan except for the butter. Stir to combine. Bring to a boil and reduce to simmer.
Simmer for 15 minutes, then add the butter until melted. Turn off the heat and let cool.
Store in refrigerator until ready to use.
While simmering, taste the barbecue sauce and adjust ingredients according to your personal taste. For a tangier sauce, add a bit more vinegar. For a sweeter sauce, add more Sukrin Gold. If sauce is too thick, add more water. If too thin, cook longer or add more paste. Flavors will meld overnight.
