THERE are white-meat people and there are dark-meat people; there are those who swear by the drumstick, thigh or breast.

And then there are skin people. They are the ones who cannot help themselves around roast or fried chicken, ripping off the crispiest bits of skin before the bird makes it to the table.

Nate Gutierrez, the chef and owner of Nate’s Taco Truck and Nate’s Taco Truck Stop in Richmond, Va., could not stop snacking on the skin left over from his roast chickens. So about six months ago, he decided to make the skin crisp on the flattop and offer it in a taco. The chicken-skin tacos sell out whenever they are on the menu.
