@Gary-T The first test batch we did was a little over the top sweet, however in the second one we tumbled it a little longer and made 100% sure all of the sugar was dissolved before adding the meat. Those two things seemed to help, the only reason for that that I could come up with was it prevented it from sitting on the outside of the meat and creating a film where it was the first thing you bit into because when we tumbled it long technically the meat took up MORE of the sugar but it deffinitely had slightly less of a sweet taste.
If anyone is looking to do this I can recommend the bold as a good base but if you are wanting to branch out and try a different seasoning I would recommend you stay with something with some heat to balance the sweetness.
