Abstract: A method of freezing perishable foods including the steps of causing one surface of a heat conducting container to contact cooled brine or a liquified gas of a low-boiling point, and keeping an object to be frozen in contact with the other surface of the heat conducting container. Thus, the freezing of the food proceeds only from the surface contacting the heat conducting container.
