Celeriac is a weird looking vegetable, whiskery and knobby, with tendril-like roots that hug the bulbous root. But whack into its tough exterior and you'll find a clean, crisp, white flesh that tastes of celery, anise and hazelnuts. Sometimes called celery root, this root vegetable is not as sweet as a carrot or parsnip and is far less starchy than a potato. Overall, its flavor is celery-like, but softer and deeper than the stalks for which it is named.
Most often, celeriac is shredded and dressed with a tart mustardy mayonnaise for the classic French celery root rémoulade. It's also terrific when boiled and mashed in with potatoes to serve with pot roast or porketta, or layered into a gratin with plenty of cheese. Cube and toss it in with roasted vegetables and it will become nicely tender-crisp. It's especially good paired with the sweet earthiness of winter squash or sweet potatoes. Slice and bake it in a slow oven with a little butter or olive oil and a sprinkle of coarse salt until it becomes soft for a fine side dish to roast chicken.
Look for celeriac near the other root vegetables at your store. Choose ones that are heavy, firm and feel solid. You'll need a good strong chef's knife to cut away the rough skin and tuft of stem.
First, trim off the tendrils, then start by cutting a slice off the top and bottom of the bulb, as if peeling an orange. Slide the knife along the sides to slice off the skin off as you go. Make sure you remove all the roots at the bottom. The stalks and leaves, if still attached to the root, resemble celery but are far stronger, so use them judiciously to season soups and stews. Celeriac tends to darken once cut, so toss with a little lemon juice if you're planning to serve it raw or in a salad. Lemon juice also helps to tenderize the starch.
Spicy Celeriac Fries
Serves 4 to 6.
Note: Ready in minutes, these are a healthful alternative to French fries. You can make them ahead and hold them in a warm oven. Be warned that they're so finger-licking good, you may find yourself eating the whole batch before they're served (so go ahead and double the recipe). From Beth Dooley.
