I just dry them off really good and cover them in oil, salt, pepper and onto the baking sheet. Lol
👀 I'll try this with this!
Parboil your chicken wings in salty water (a brine almost?) for about 8 minutes then blast at 450 in the oven until crispy. So good.
Another food science tip is to add baking soda when doing the par boil!
