Preheat oven to 425? In a small bowl, mix all of the dry ingredients together. Stir well to combine. Place wings in a medium bowl. Pour the butter and sriracha over the wings and toss to coat them well. Sprinkle the spice mix in, rubbing so that all the wings are completely covered. Spread the wings out onto a non-stick baking sheet, or one that you've covered with foil. Bake for 30 minutes, until browned and starting to crisp on top and at the edges. Remove from the oven and devour at will.
