Which of the following is a cooking method that uses dry heat?

Grilling is a cooking method that utilizes dry heat, making it distinct from other cooking techniques that involve moisture. In grilling, food is placed over a direct heat source, typically over an open flame or hot coals. This high-temperature cooking causes the exterior of the food to sear, which not only enhances flavor through the Maillard reaction but also creates those characteristic grill marks and a crisp texture.

In contrast, sous vide involves cooking food in a sealed bag submerged in water at a regulated temperature, which is a wet heat method. Boiling uses the high temperature of bubbling water to cook food, and steaming also employs water vapor, making both of these methods reliant on moisture. Therefore, grilling stands out as the appropriate choice for a cooking method that employs dry heat.
