Cooking with high heat involves two main techniques: searing and broiling. Searing is a cooking technique that uses very high heat to quickly cook the outside of a food item, while leaving the inside relatively uncooked. Broiling is a similar technique, but it uses direct heat from an overhead source, such as a broiler or grill, to quickly cook the food item. Both techniques are used to create a flavorful, crispy exterior on the food item while keeping the inside moist and tender.
