The ice cream is placed in a vacuum chamber and frozen until the water crystallizes. The air pressure is lowered, creating a vacuum, forcing air out of the chamber; next heat is applied, vaporizing the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a perfect freeze-dried ice cream slice.Ingredients:Milk fat, nonfat milk, corn syrup, whey, stabilized and emulsified by mono and diglycerides, guar gum, cellulose gum and carageenan, artificial flavor, and vegetable annatto color.
