Liquids to be dispensed as "frozen" or "slush" beverages are rapidly cooled to a suitable target viscosity or percentage of frozen, by maintaining a flow of liquid nitrogen through one or more heat exchangers, counterflowing the beverage to be cooled from a reservoir to a dispenser, and controlling the flow of liquid nitrogen to achieve the target viscosity or percentage of frozen of the beverage to be dispensed.
