I used to do that with mine, until I found another recipe from a cook I trust, that recommends boiling them for several minutes to render out some of the fat, then baking them. She swears it gets them crispier than the baking powder method.
That’s how I prepared the most recent wings I posted here, and I have to say, I do agree with her, and MrsT, who grew up on “authentic” hot wings, swore they were the best she’s had. The skin was crispy, like thin sugar glass, but they didn’t have to bake too long to achieve that, so the meat was still very moist, even with no sauce added.
