Recipe of the week: Potato and Celeriac Gratin

One look at raw celeriac “could kill appetites,” said Wendy Donahue in the Chicago Tribune. The ungainly appearance of this tuber probably explains why American cooks typically avoid it “despite its long tradition in the Old World as both an aphrodisiac and a winter staple.” In its flavor, celeriac—or celery root—actually tastes as if it’s “a cousin to anise, carrots, parsley, and parsnips.”
