Both sauces I made here at home have had very similar bad tastes. I did let the sauce simmer like I was supposed to, and did all of the right measurements (except I cut the entire recipe in half due to just trying it out) The sauce when done had an extremely strong scent to it that would singe the nose hairs and water your eyes if you didn't pull away immediately like I did, lol. And the taste was just as bad. Almost tasted like really screwed up ketchup. I will say the ketchup I'm using is a store brand ketchup and is a tad stronger than ketchup like Heinz, but I can't imagine that this minor different would make this sauce taste so bad.
And neither sauces I made (the other one was quite similar to Jeff's just not as much ketchup) really had that BBQ type of flavor I'm looking for. Maybe some of you guys could enlighten me or tell me where I could possibly be going wrong?
