Gremolata, a mixture of herbs, garlic and lemon zest, is stuffed under the skin, contributing its extraordinary fragrance to the chicken. To ensure moist and succulent meat, the skin is left on for roasting, but removed before carving. This is an excellent treatment for all kinds of poultry; for a turkey, make a double or triple batch of gremolata. Serve with plenty of Garlic Mashed Potatoes to soak up the sauce.
