spread 4 1/2 cups kettle cooked potato chips, on a rimmed baking sheet. Bake at 350° until oil appears, 6 to 7 minutes. Meanwhile, mix together 1/2 cup very finely grated Parmigiano-Reggiano cheese, about 1 ounce, 1/2 teaspoon paprika, and 1/8 teaspoons cayenne pepper. Remove chips from oven, and immediately sprinkle with cheese mixture. Serve warm or at room temperature. Serves four.
