What cooking method involves cooking food uncovered without added liquid or fat?

The chosen answer is correct because the method described involves cooking food using dry heat without the addition of liquid or fat. Dry heat cooking methods rely on hot air or direct heat to cook the food, which includes techniques such as baking, roasting, grilling, and broiling. These methods not only preserve the natural flavors of the ingredients but also promote browning and caramelization, enhancing the overall taste and texture of the dish.

In contrast, steaming employs moisture in the form of steam to cook food while keeping it covered, boiling involves cooking food in a pot of liquid, and sautéing requires the use of a small amount of fat in a pan over moderate to high heat. Each of these methods is distinctly different from dry heat cooking, as they involve either moisture or added fats during the cooking process.
