Abstract:
1. A method of preparing an individual-size customized ice cream serving to be sold on demand comprising the steps of: a. mixing a predetermined amount of an ice cream premix, an ice cream flavoring agent, and one or more mix-in foods in a first eight quart metal bowl, the first bowl having a center and a continuous side that forms an inner diameter of the bowl; b. dispensing a predetermined volume of liquid nitrogen through a phase separator into the first bowl to float on top of the premix, the volume of liquid nitrogen being determined by considering the volume and desired temperature of the serving of ice cream to be prepared, the volume of liquid nitrogen being at least sufficient to cover the premix and to cause an upper portion of the premix to freeze and form a crust on the boundary of the premix and the liquid nitrogen; c. repeatedly breaking the crust formed at the boundary using an ice cream spade and scraping the premix off the side of the first bowl to raise each crust boundary above the liquid nitrogen and plowing each successive crust boundary into the center of the first bowl so that the liquid nitrogen flows under each successive boundary and boils from underneath the solid crusted boundary of the premix, the boiling thereby causing the premix to overrun and to freeze until all the premix, flavoring and mix-in foods reach an equilibrium temperature as ice cream having a completely frozen texture throughout; and d. dispensing the ice cream into a serving container.
