Why this recipe works best on a clean grill
A clean grill makes this recipe easier because the grates release food evenly, the heat moves predictably, and old grease does not smoke over the fresh ingredients. When carbon buildup sits on the grate, it can leave bitter flavors, create flare-ups, and make delicate foods stick right when they should sear.
Before cooking, preheat the grill fully, scrape the grate with a bristle-free tool, and lightly oil the surface. If your grill has yellow flames, heavy smoke, stubborn hot spots, or a greasy smell before the food goes on, it may need a deeper cleaning before your next cookout.
