Abstract

In a method for cooking food in a container, in particular in a bag, the container, during heating, is opened at a particular overpressure of the medium and closed when the overpressure drops. A closing device is connected to the container and equipped with a pressure relief valve by means of which the container is opened at a particular overpressure of the medium and closed when the overpressure drops. The closing device includes at least one inner elongate retaining element and at least one sleeve body which surrounds the retaining element. The container is provided with an opening, and fed between the retaining element and sleeve body and through a longitudinal slit in the sleeve body. The retaining element and its surrounding sleeve body form the pressure relief valve. Optimal cooking of the food introduced into the container is achieved and fast preparation of the food is possible.
