Root Vegetable

Baking potatoes, boiling potatoes, new potatoes, and fingerling potatoes—there are many kinds of each to choose from, some yellow, some blue or red. The red-skinned potatoes oft en called boiling potatoes have dense, white, waxy flesh that holds its shape when boiled. They won’t do very well for baking and make terrible mashed potatoes, turning gluey when mashed. Baking potatoes usually have light brown skins with white flesh that is dry and fluff y when cooked. These are best for baking and for French fries. Kennebecs and russets are common varieties. The tastiest, most versatile potatoes are the yellow-fleshed varieties such as Yellow Finn, German Butterball, and Yukon Gold. The flesh of these potatoes has a texture between that of a baker and a boiler. They have enough waxy starch to hold together when boiled, but not so much that they can’t be mashed—and best of all they are full of flavor, much more so than any white-fleshed variety. New potatoes are those that are dug while the plants are still green in the fields and have thin shaggy skins. They are a real treat. Fingerlings are smaller potatoes shaped, as you might guess, like long thin fingers. Some delicious varieties to try are Russian Banana, German, and Ruby Crescent. Select potatoes that are firm and free of discolored spots. Don’t buy potatoes that have green on the skin. This is caused by exposure to light and may indicate the presence of solanine, which is toxic. The green may be peeled away, but it is better to avoid having to do so. Store potatoes in a bag or cupboard away from any light. New potatoes and fingerlings never need to be peeled; just wash them well before cooking. Other potatoes should be peeled, depending on the recipe and your wishes. Once peeled, potatoes should be kept submerged in water to keep them from turning brown. I like this best when the potatoes are sliced quite thin (a mandoline makes this easy): that way the potato slices are less likely to curl up and burn on the edges. Yukon Gold and other waxy, yellow-fleshed potatoes keep their texture in a gratin; floury potatoes like russets fall apart.

Garlic purée is delicious stirred into mashed potatoes or a soufflé base. It makes a tasty compound butter with a bit of salt and will make a gravy taste sublime.

This is a gratin made with a thin white sauce (béchamel), rather than one layered with milk, or with cream and broth. I use this method to cook other vegetables, such as cauliflower, wilted greens, or asparagus.

Fennel is among the most versatile of vegetables: it’s good whether it’s eaten raw in salads, or cooked in any number of ways, and I use it as an aromatic vegetable, often instead of celery, in mirepoix (diced carrot, onion, and celery) and other preparations. Cultivated fennel forms a compact, pale white bulb that is topped with fibrous green stalks and feathery leaves. The flavor is reminiscent of anise or licorice. Look for firm, undamaged bulbs that have no signs of drying or shrinking. The fronds should be fresh and vibrant. To prepare fennel, trim away the darker fibrous stalks and bottom end, and remove any outer layers that are tough or blemished. Fennel should be cut close to the time it is needed, as it will oxidize and brown over time. Cover cut fennel with a damp cloth to protect it. Many recipes ask you to remove the core, but I don’t find it necessary; on the contrary, I like the taste of the core and find it quite tender. The feathery dark green fennel leaves can be stripped from the stalks and chopped to use as a flavorful garnish. Wild fennel is an uncultivated variety of fennel that does not produce a bulb. Its leaves, flowers, pollen, and seeds are all very flavorful and useful in stuffings, marinades, garnishes, and sauces. If it grows in your region, forage for it in the wild.

The flavors of celery root and potato combine so perfectly that they form a new flavor all its own. Not only are they delicious together in purées, but they also make an excellent gratin (see Potato Gratin, page 318).

Algerian in origin, this recipe makes a colorful, tasty hors d’oeuvre. Serve it at room temperature with toasted croutons or pita bread and marinated olives. Warm, it makes a great side dish with baked fish and Chermoula (page 233).

This pie makes a good picnic breakfast.

A panade is a thick soup made of layers of bread, vegetables, and cheese moistened with broth or water and baked until soft and golden. This onion panade is a hearty, homey soup bursting with sweet onion flavor.

Young turnips with their greens are in the markets in spring and fall. The two together make a delicious soup or side dish.

Tabbouleh is a Lebanese salad made with bulgur wheat, chopped herbs, and tomatoes. It is a spectacular salad, green and fresh, with more herbs than grain. Bulgur wheat is made from wheat grains that have been parboiled or steamed and then dried. It requires only quick cooking or soaking.

Semolina, coarsely ground durum wheat, turns simple, homemade chicken broth into a more substantial, silky textured soup.

Fennel makes a very delicate salad when sliced paper-thin. It can be difficult to cut the fennel very thin with a knife, so instead I reach for my plastic Japanese mandoline. But watch your fingertips and use the guard!

This salad tastes best when the carrots have time to marinate and absorb the flavors of the spices.

My daughter always loved this salad and I would often make a tiny version for her lunch and change the shapes for variety: grated, thin curls (cut with a peeler), matchsticks, or slices.

Yellow potatoes such as Yellow Finn and Yukon Gold have very good flavor and texture for potato salad. Don’t use baking potatoes such as russets; they will fall apart.

Serve this winter salad alongside other little salads, such as marinated beets, carrot salad, or arugula salad.
