An ice shaver/blender control apparatus and method includes monitoring the operation of a blender motor as a measure of monitoring the quality and results of blending. By connecting a feedback sensor to the motor, it is possible to determine whether a blend process is complete. It is also possible to identify when cavitation is occurring or about to occur. In another aspect, the blender controls are directed to an improved method for portion blending. The method includes a two-step query to the user to determine both a predetermined portion size and the number of portions to be blended.
