Thermomix® Slow Cook and Sous-vide modes introduce longer cooking times. The blade cover is used to protect softer ingredients, or sous-vide bags, from coming into contact with the moving blades of the mixing knife. This clever accessory covers the blades without preventing stirring, resulting in even heat and gentle cooking. Use the blade cover with the Slow Cook and Sous-vide modes to make the most of the precise temperatures of Thermomix®. Whether you’re slow cooking a stew or preparing a gourmet sous-vide dish, Thermomix® makes it effortless.
