Celeriac, also called celery root, knob celery, and turnip-rooted celery (although it is not a close relative of the turnip), is a variety of celery cultivated for its edible stem or hypocotyl, and shoots. Celeriac is like a root vegetable except it has a bulbous hypocotyl with many small roots attached.
Raw celeriac is a great addition to salads. Celeriac remoulade is the classic preparation, a simple salad of celeriac, mayonnaise, mustard and lemon juice. But it’s worth branching out and trying some more unusual recipes like Nathan Outlaw’s Root vegetable slaw or Paul Ainsworth’s Celeriac, apple and fennel slaw.
Celeriac is worth cooking, as well. You can treat it like any root veg. Roast it as you would potatoes. Boil it and mash it with other root vegetables, or serve it on its own. It should take around 20 minutes to cook in boiling water until tender, and 30–40 minutes in a 180°C oven.
