This video shows you how to make mashed celery root and potatoes. The potatoes add texture, richness, and a nice starchy quality to mashed celery root. You’ll mash your taters and celery root with a potato masher—no need to break out the electric mixer. Flavor your mash with butter, a little cream, a touch of nutmeg, pepper, and salt. Watch the video, then get Chef John’s recipe for Celery Root and Potato Puree. Try this with rich braised or grilled meats. It’s a terrific contrast.
