A system and method for making frozen, blended confections utilize liquid nitrogen to partially freeze the confection. A liquid or slurry is first placed in a blender and during blending, liquid nitrogen is introduced at a controlled rate so that the liquid partially freezes and the liquid nitrogen is exhausted out the top of the blender in a visually exciting manner. The blending action and the delivery of liquid nitrogen is synchronized by a computer-controlled algorithm to ensure consistent results.
