"When you have a dirty grill, it imparts unwanted flavors onto your food," Burke says. A clean grill also ensures that delicate meats, like fish and sausages, are less likely to stick to the metal grates and get torn or ruined. In lieu of a ritual scrubbing for every meal, Burke offers a novel shortcut for keeping your grill surface tidy: "Wrap and fasten a piece of cloth on a paint roller. Roll it in olive oil and then roll it over the grill prior to putting meat or fish on the grill." To state the obvious, don't make it sopping wet, or you risk an oil fire. But you'll be amazed at how easy cleanup is afterward.
