The secret's in the crust, which uses crushed sourdough pretzels for extra crunch.

Crunchy Buffalo Wings

Preheat oven to 425 degrees. Line baking sheet with foil; place a wire rack on top of foil and spray with nonstick cooking spray.

Pour pretzel crumbs into a pie plate or similar container.  In a small bowl, whisk egg whites and hot sauce.  Dip wingettes in egg white mixture, then roll in crumbs; firmly pat crumbs so they stick. Place on rack on baking sheet.

Bake 45 minutes or until crispy and golden.
