The BBQ sauce we like is Bullseye. It wins most of the store bought taste tests.
Also, you can mix most BBQ sauces to make them more to your liking. I think they are too thick, and prefer more of a glaze. Adding something like pineapple juice is not too sweet, and will thin it down. Also, If my DH makes pulled pork, or brisket, I mix half of the juice with equal parts bbq sauce. This way you get the taste of what you just made, but don’t have to make your own bbq sauce.
You could also look up a recipe for KFC kopycat bbq sauce. See what is in it that and make your own, or add figure out what ingredient is missing in your bottle brand and add it.
An angel. Many thanks. Good useful suggestions.
