Mixing leftover fridge sauces/condiments and such is an easy cheat for sure. But I think adding the honey to the sauce was the thing that did the trick here. I will be doing that again. Nice and sticky wings, with a honey sweet that took the hot edge off.
It'll be a long time before I cook thawed wings again. I never see just first and second pieces, just entire wings. And separating them is a pain. But a bag of frozen, and for whatever reason that's how they come, as they should (no tips, and separated.)
Of course, brining/marinating etc isn't going to happen if frozen, but they cook "bare" OK. Some wanted to stick a little, but I'd left them alone for a good 40 mins before turning them. Probably should have gotten to them sooner. But once they were done and then sauced at the grill, it was magic time.
