Celeriac

Overview

Also called celery root, celeriac is an ugly-duckling root vegetable with a complex, nutty celery flavor that shines in cold-weather cooking. Beneath its knobby exterior lies creamy white flesh that is equally delicious raw or cooked. A staple of French cuisine, it is the star of céleri rémoulade and adds depth to soups, gratins, and purees.
