Typically, celeriac is harvested when its hypocotyl is 10–14 cm in diameter.[4] It is edible raw or cooked, and tastes similar to the stalks (the upper part of the stem) of common celery cultivars. Celeriac may be roasted, stewed, blanched, or mashed. Sliced celeriac occurs as an ingredient in soups, casseroles, and other savory dishes.
