A European staple gaining popularity here, celeriac (a.k.a. celery root) produces big, solid knobby roots just above the ground. Once peeled, the white flesh has the flavor of mild celery and parsley. This German-bred Prinz offers nutty, sweet flavor, fine texture and reliable, big yields that hold for harvest well in the garden. Shred celeriac for salads with a mayonnaise, lemon and mustard dressing, or cut up and simply roast or braise or add to soups and stews.
