Weeell, I'm eating it now, but it doesn't have that yummy plum flavor I'm used to from Chinese restaurants. I think that's because I used plum sauce from a jar, so the next time I think I'll look for plum jam and make my own sauce. I also didn't make enough sauce. The recipe was supposed to cover two chicken breasts, but it was barely enough for one.
So, edible, but needs a lot of tweaking.
I didn't baste the chicken breasts with the sauce. I just pooled a little sauce on the bottom and laid the chicken breast on it, and poured the rest of the sauce over it. I will say, it certainly caramelizes nice, though.
