An immersion blender? Maybe now 🤷‍♂️, but apparently it was invented in Switzerland.

It’s also called a stick blender. It’s a wand with a small spinning blade on the end. You put it into the food to blend it instead of putting the food into a blender. You can blend hot soup right in the pot, emulsify sauces and spreads, froth milk, make smoothies, etc. Since you can move the stick around, it handles thicker blends that would stick to the sides of a conventional blender.
