A blender for home food preparation is improved by the incorporation of electronic motor control circuitry responsive to a microcontroller. The microcontroller includes memory for storage of data and programmed instructions. The programmed instructions permit a user to select from a plurality of blending speeds and define a pre-determined end time. Use of a pre-determined end time produces a two-speed blending cycle. The programmed instructions determine the length and energy level associated with each portion of the two-speed blending cycle. A user can stop the blending cycle at any time, with or without a pre-determined end time. Safety features include a pre-determined maximum motor run time, top jar load detector and auto shut down after a period of inactivity. The pre-determined end time from a previous blending cycle is stored in memory, allowing the microcontroller to reproduce the duration of the previous blending cycle.
