Sous Vide is a trending cooking technique. Simply place the food in a sealed bag and place into a vessel with water and turn on a Sous Vide Immersion Circulator Head that will heat the food to the precise temperature and exact time. All food will retain all nutrients and will not shrink. Some Sous Vides have safety features that will not cause the equipment to overheat or if the water level is too low to operate.
