When to foil, when to skip

Using foil on a public charcoal grill can be a useful trick for enhancing your cooking experience. However, it may not be suitable for other types of grills, like gas grills, as it can block airflow and potentially harm the appliance's long-term performance. If you're grilling at home, you can forgo the foil for safety reasons, as it's easier to clean your own grill thoroughly.
On the other hand, applying a layer of foil on your home charcoal grill can be an excellent technique for preparing certain foods. For example, aluminum foil can help distribute heat more evenly, making it easier to cook smaller items like shrimp or diced peppers. You don’t need to cover the entire cooking surface to reap the benefits of using foil. For instance, when grilling corn, wrapping it in foil allows it to steam while cooking. You can also use foil packets for more delicate proteins, such as cod, which might otherwise break apart on the grill. This method enhances the flavor of your fish while preventing it from sticking to the grill.
