A method is provided for storing a cooked food in a flexible-walled container having an opening. The method includes placing a quantity of food in a flexible-walled container and submerging at least a portion of the container in a liquid with the opening being located so that liquid does not enter the opening. At least the lower portion of the container is maintained in the liquid and the food is maintained in the container below the surface of the liquid. The liquid collapses the container to seal the container. The temperature of the liquid may be maintained at a non-ambient temperature to heat or cool the food as it is stored. The method may also include storing the food adjacent a work surface, or at a remote main vat and transporting the rack to the work surface at which a serving that includes the food is prepared.
