Immersion blender Bosch Serie 4 MSM4W421 Black White

The Bosch Serie 4 MSM4W421 immersion blender combines an 800 W motor with a compact, two-tone black and white design to perform everyday blending and mixing tasks. The appliance features a 1.4 m cord for flexible placement, a durable plastic housing and stainless steel blades for reliable performance, and compact dimensions (57 mm width, 78 mm depth, 385 mm height) that simplify storage and handling in kitchens with limited space.

Advantages

Stepless speed control using buttons and a lever enables precise adjustment for delicate emulsifications and more vigorous blending. The stainless steel blade construction offers corrosion resistance and long-term cutting efficiency. Compact and lightweight construction at 1.3 kg improves manoeuvrability and storage convenience.

How to use

Insert the immersion blender into the ingredient container or pot, ensuring the blades are fully submerged before switching on to avoid splashing. Select the required speed using the control buttons and adjust with the lever during operation for finer control. Move the blender gently through the mixture with a slight up-and-down motion until the desired consistency is reached. After use, switch off and unplug the appliance, allow components to cool, then detach the blending shaft if applicable and clean according to the manufacturer’s instructions.

Usage recommendations

For best results when blending hot liquids, use a deep pot to reduce splatter and start at a low speed, gradually increasing as the mixture emulsifies. Avoid prolonged continuous operation to prevent motor overheating — allow short cooling intervals for heavy tasks. Hand-wash detachable parts that contact food and wipe the motor housing with a damp cloth; do not immerse the motor unit in water.
