A stick blender, also known as an immersion blender, is a handheld kitchen appliance used for blending, pureeing, and mixing food directly in a pot or bowl. Its design features a long shaft with rotating blades at the end, allowing users to blend ingredients without transferring them to a separate container. This makes it convenient for soups, sauces, and smoothies. Stick blenders are typically lightweight and easy to operate, often featuring multiple speed settings for different tasks. They are also easy to clean, as most models have detachable blending heads that can be rinsed or placed in a dishwasher.
