You can quickly set up your barbeque for high-heat searing or low-and-slow cooking with Weber's Charcoal Heat Controller for 57 cm kettle charcoal barbecues. It consists of a cone and diffuser ring, which takes the guesswork out of barbecuing for beginners and raises the bar for seasoned gardeners. When using charcoal briquettes, the cone sets the charcoal for up to 7 hours of low-and-slow cooking, and the diffuser ring distributes heat evenly over the entire grilling surface, giving you plenty of area for larger dishes like ribs, hog shoulders, and more. The cone can be used to produce both efficient, convective heat for wonderfully crispy wings, meats, and vegetables, as well as extremely high heat for searing.
