With Weber’s Charcoal Heat Controller for 57 cm kettle charcoal barbecues, you can easily set up your barbecue for high-heat searing or low-and-slow cooking. Comprised of a cone and diffuser ring, it reduces the guesswork for less experienced barbecuers and adds a new level of mastery for garden pros. The cone positions charcoal for up to 7 hours of low-and-slow cooking when used with charcoal briquettes, while the diffuser ring provides even heat across the entire barbecuing surface, giving you plenty of room for larger foods like ribs, pork shoulders and more. The cone can also be used to create extremely high heat for searing as well as efficient, convection heat for perfectly crispy wings, meats and veggies.
