Cooking techniques refer to the various methods used to prepare food. Common techniques include boiling, steaming, baking, and grilling. Each method affects the flavor, texture, and nutritional value of the food. For example, steaming retains more nutrients compared to boiling, where some nutrients may leach into the water. Different techniques can also enhance the taste of ingredients. Sautéing involves cooking food quickly in a small amount of fat, while roasting uses dry heat to develop rich flavors. Understanding these techniques allows cooks to create a variety of dishes and improve their culinary skills.
