Designed to fit all Bosch stand mixer/kitchen machines with model numbers begin with UM4 or MUM4... (Compact model), this 4-cup (1-liter) blender is made of virtually unbreakable plastic with a stainless-steel blade. (The blender has no motor and cannot operate independently of the kitchen machines.) The sturdy, four-pronged blade chops, blends, mixes, and purées foods and drinks and easily crushes ice. The lid has a cavity and hole for adding oil to salad dressings and other emulsions. The blade is permanently attached so cleaning the interior can be accomplished with hot water, a drop of liquid soap, and a brief whir of the motor. The blender stands 9-1/2 inches high and is dishwasher-safe. Calibrations marked on the exterior are in liters and cups.
