Immersion Blender

An immersion blender is a handy, compact addition to a one-butt kitchen.  Most of them have several attachments, including a blender, whisk, and food chopper. Some of the newer ones even have a milk frother for making lattes. With the blender, you can whip up smoothies and protein drinks, puree veggies for soups, make whipped cream, and juice a watermelon. The whisk can be used to whip egg white into peaks for various recipes.
