Immersion blender!

It takes up less space than a big blender. It has so many uses: smoothies, sauces, puree hot things right in the pan, etc.

It's easier to clean than a regular blender: put water in a cup with soap and blend it.

Then wipe off anything else with a sponge. (You can probably put it in the dishwasher but I don't have one of those)
