Chef-owner Prince Johnson of Prince on Delaware brought a little spice to Old New Castle last fall when he trotted out his “Outrageous” chicken wings. Johnson conjured the recipe while working as private chef to the president of Swarthmore College. Johnson wanted to wow the diverse diners who visited campus, so he consulted a Chilean staffer about South American cooking. Johnson consequently added dry chili peppers to his wing marinade to give them the proper kick. The plump wings, from free-range chickens raised on an Amish farm in Lancaster, Pennsylvania, are fried and served with sour cream. The juicy appetizers have become a customer favorite.
