Potato and Celery Root Gratin with Gruyère

With a flavor that echoes common celery, the gnarled, knobby brown root bulb known as celery root, or celeriac, also has a pronounced nutty, earthy taste. It’s often paired with potatoes, as in this rich, creamy gratin. Use a mandoline or food processor to cut the celery root and potatoes into thin, uniform slices.
