The duration required to grill ears of maize, encased in a metallic wrapping on a barbecue, is the central focus of this exposition. The cooking time directly impacts the tenderness and overall palatability of the corn. Factors influencing the appropriate cooking period include the grill’s temperature, whether the corn is pre-cooked, and personal preference for the final texture. An example: A grill heated to medium (350-450F) typically necessitates approximately 15-20 minutes for optimal cooking of foil-wrapped corn.
Accurately gauging the necessary grilling period is important for achieving desired results. Under-cooked corn can be tough and lack sweetness, while over-cooked corn can become mushy. Historically, grilling corn directly on the barbecue was common, but wrapping it in foil offers a protective layer, preventing charring and retaining moisture, leading to a more consistently cooked and flavorful outcome. This method enhances the eating experience, making it a popular choice for barbecues and outdoor cooking events.
