A sous vide machine is a kitchen appliance used for cooking food in a precise temperature-controlled water bath. The process involves sealing food in a vacuum bag and immersing it in the water, allowing it to cook evenly and retain moisture. This method enhances flavors and ensures that food is cooked to the desired doneness. Sous vide cooking is popular among both home cooks and professional chefs because it simplifies the cooking process and reduces the risk of overcooking. Many sous vide machines come with digital controls, making it easy to set the temperature and cooking time for various types of food.
