Heat cooking methods involve applying heat to food to transform its texture, flavor, and nutritional value. Common methods include boiling, steaming, baking, grilling, and frying. Each method uses different temperatures and techniques, affecting how food cooks and tastes. For example, boiling involves cooking food in water at high temperatures, while steaming uses vapor to cook food gently. Baking uses dry heat in an oven, and grilling cooks food over an open flame. Frying involves cooking food in hot oil, creating a crispy texture. Each method has unique benefits and is suited for different types of dishes.
