Automatic Saucier

From the site:
This is the only device that automatically stirs sauces, leaving you free to prepare other parts of the meal. The device stands in a sauce on three stainless steel legs with silicone rubber feet and autonomously spins and revolves smoothly around the pan, mixing ingredients and infusing their flavors.

Or you could just stir it with a wooden spoon. It’s up to you.
