1. A method of making an ice cream product, comprising:
placing ingredients of the ice cream product into a container having an open top;
using a control valve to selectively dispense a cryogenic liquefied gas from a cryogenic tank into the container through a line having an opening mounted above the ingredients of the ice cream product;
mechanically mixing, with a powered mixer, the ingredients with the cryogenic liquefied gas in the open top container while flowing the cryogenic liquified gas through the line and through the opening mounted above the ingredients into the open top container containing the ingredients to produce the ice cream product;
freezing, with the cryogenic liquefied gas, the ingredients while mixing the ingredients with the powered mixer to produce the ice cream product; and
transferring, after freezing, the ice cream product from the container to a serving container,
wherein a sufficient amount of the liquefied gas controlled by the control valve is introduced into the container to produce a visible amount of cryogenic vapor flowing from the open top of the container, and
wherein the powered mixer comprises a support having a bottom surface positioned on a work surface, the bottom surface being configured to support the container above the work surface.
