We have an old saying here at Weber that is considered the golden rule in grilling. If you're lookin', you ain't cookin'. Every griller should live by this mantra and always remember it as a golden rule upon which great grillers are built.
So what does it mean? Simple, keep the lid closed when you are grilling. Grilling with the lid open is a bad habit which is done by amateur grillers. Weber grillers know the key to perfect back yard grilling is keeping the lid closed. Grilling with the lid closed is a very simple tip which many people overlook. If you are looking to raise the level of your grilling abilities this step is essential. By keeping the lid open the grill will lose heat and will cause your foods to be grilled longer. By keeping the lid closed you allow the Weber grill to do what it was designed to do, grill!!! By keeping the heat inside the grill, food will grill faster and be more flavorful.
One major advantage to grilling with the lid closed is controlling flare ups. Weber grills are designed and engineered to eliminate flare ups. This is done by our legendary flavorizer bar system. The flavorizer bars system is the heart of Weber® Gas Grills. A single row of Flavorizer® Bars eliminates annoying flare-ups by vaporizing juices and creating the smoke that gives every meal that barbecue flavor. I can't even tell you how often people ask me how to control flare-ups and how to get better grilling results. Grilling with the lid closed is the best possible way to achieve both. I know is seems very simple but keeping the lid closed is the single best way to grill foods properly and get the best possible grilled results. For the charcoal lovers out there, the genius of a Weber kettle's design is that it allows hot air to circulate throughout the grill. This circulation allows for perfect convection style grilling. By keeping the lid closed throughout the grilling process flare ups are virtually eliminated and food is grilled to perfect.
Again it's important to recognize that Weber grills are designed and engineered to grill your food to perfection. I know it might be difficult at first but one of the most important things you can do is trust your Weber. I promise it will not let you down.
