Welcome to DC, your 1 stop, foodie talk forum!
Well, here is what I have done in the past...
So you got yourself some good dry rub, bloom it in a little bit of simmering water, and I do mean a little, and then reduce. Thicken with a little bit of corn syrup, toss to coat. For an added bonus, throw wings on a grill to get a little nice and crusty, then toss in sauce.
As far as smooth, well, I dunno. I love the combo of the textures, but if simmered, the rub/herbs should soften up a bit.
BTW,if you do NOT wanna use corn syrup, substitute Mae Ploy Sweet Thai Chili Sauce. Nice lill flavor kick too.
