Celery root can widely vary in size from small to large, but typically averages 10-14 centimeters in diameter and is globular, slightly flattened, and lopsided in shape. The gnarled corm is rough, brown, and thick, covered in small rootlets giving it a creviced appearance. Underneath the root rough exterior is a crisp, ivory to white flesh that is dense and firm. When raw, Celery root has a crisp consistency that transforms into a smooth and tender texture when cooked, similar to the flesh of the cooked potato. Celery root has a nutty, earthy, and slightly sweet flavor with notes of celery and parsley. Connected to the corm, the plant produces thin, green stems that resemble celery and are topped with small, serrated leaves.
Celery root can be eaten raw and is popularly grated or spiralized and tossed into salads, grain bowls, or fruit salads. The corm is also utilized in many cooked applications such as blanching, boiling, mashing, stewing, and roasting. Before cooking, the rough skin should be removed, and the white flesh should be soaked in a milk bath or in acidulated water to prevent the flesh from browning. Once prepared, Celery root can be utilized as a non-starchy substitute for potatoes for any meal and can be prepared similarly. Celery root can be cut into fries, mashed, roasted as a vegetarian steak, boiled and diced for a take on potato salad, pureed for soup, or sliced and baked into chips.
The corm will keep up to three weeks when wrapped in a paper towel in an unsealed plastic bag and stored in the refrigerator
