What is celery root?
Celery root, also called celeriac, is an edible root vegetable in the celery family. The stalks and leaves of celery root strongly resemble celery, although they are not very good to eat. Celery root itself is a lumpy tuber of unprepossessing appearance, although it packs an excellent taste and is used throughout European cuisine, especially in France. Celery root is beginning to be popular in the United States, with more cooks discovering its myriad uses.
