A method for preparing a flavored slurried confection includes the use of a disposable serving container holding an individual serving of a neutral flavored mix which has a
freezing point temperature lower than normally found for that of water. A large supply of the mix filled containers is stored in a storage freezer for maintaining the neutral flavored mix at a storage temperature, such as is typical of a
food storage freezer for a restaurant. A desired quantity of the mix filled containers is then transferred from the storage freezer to a
tempering freezer, generally close to a preparation and serving area, for maintaining the neutral flavored mix at a desirable blending temperature. The mix filled container is then removed from the
tempering freezer for preparation of a flavored confection, such as a flavored shake. In preparing the flavored confection, a small quantity of a selected syrup is pumped from a selected bag-in-the-box styled
carton into the mix filled container for blending the selected syrup with the neutral flavored mix while the mix remains chilled at the blending temperature. The small quantity of syrup adds provides the selected
flavor to the neutral flavored mix for forming the flavored slurried confection which is then served within the disposable serving container.
