A container for rapidly cooling and holding foods at safe temperatures for extended periods of time which includes an upwardly opening inner container in which foods may be placed and another container surrounding the inner container. An enclosed chamber is formed between the bottoms and side walls of the inner and outer containers and is provided with a slow-to-freeze, slow-to-thaw gelatinous material which may be frozen by placing the container in a low temperature freezer. The container is further characterized in that the bottom and walls of the inner container provide insulating properties which control the rate of heat transfer between the gelatinous material, when frozen, and foods placed in the container and further characterized in that the bottom and walls of the outer container provide insulating properties which substantially retard heat transfer between the gelatinous material, when frozen, and the ambient air which surrounds the container.
