A steam oven is a kitchen appliance that uses steam to cook food, providing a moist cooking environment. This method helps retain nutrients, flavors, and textures, making it ideal for vegetables, fish, and grains. Steam ovens can be used alone or in combination with traditional heating methods, offering versatility in cooking. These ovens typically have a water reservoir that generates steam during the cooking process. Many models also feature settings for different types of food, allowing for precise temperature and humidity control. Popular brands include Bosch, Miele, and Electrolux, which offer various sizes and functionalities to suit different cooking needs.
