Sweet Potato

GOOD TO KNOW Puréed vegetables give soup the same sort of velvety consistency that cream does. Vegetables like sweet potatoes, because of their starch content, also lend body to soups and stews.

WHY IT’S LIGHT Low-fat yogurt, garlic, and vinegar are combined in a creamy, tangy dressing—without a drop of oil. Walnuts roasted with the vegetables add satisfying crunch and not much fat.

Sweet potatoes and yams are virtually inter-changeable in the kitchen. Sweet potatoes have pale-yellow, dry, nutty-flavored flesh. Jewel and garnet are the two most common kinds of yam; both have reddish to purple-colored skin and brilliant orange, sweet, moist flesh. Look for firm, unblemished sweet potatoes or yams. They continue to sweeten after harvest, but they don’t store well and they tend to spoil fairly quickly. Wash them and roast them whole in the skin or peel them to roast, steam, or fry.

Sweet potatoes cooked in piloncillo (unrefined solid cane sugar, usually found in the shape of small truncated cones) are sold as candy at Mexican mercados. They are way too sweet for me, but there’s no denying the spud’s versatility. Here I highlight their savory flavor by mashing sweet potatoes with a little butter and sage in a great fall dish that works well with roasted turkey. Feel free to use skim milk instead of whole milk, if you must, but keep that stick of butter!

Making your own gnocchi is not as difficult or as time-consuming as you may think. Don’t be afraid to try it! Sweet potatoes, a favorite Mexican ingredient, give the dough for these gnocchi a subtle sweetness and added nutrients (sweet potatoes are rich in fiber and vitamins A, B, and C). A simple butter-sage sauce is all you need to finish off this satisfying dish.

The idea for this dish comes from a chef at culinary school who liked to bread salmon with shredded russet potatoes. Sweet potatoes add a whole new dimension to this delicate crust—a perfect counterpoint for the smoky sauce.

This caribbean-inspired sweet potato soup is always appropriate in hot weather and makes an unusual starter for a meal off the grill. Serve it hot or cold; by all means chill it in warm weather, but remember it in winter. Whether you’re reheating it or serving it cold, make the soup as far in advance as you like, up to a couple of days. If you’re so inclined, you can make this soup even richer and sweeter by using half chicken stock and half canned coconut milk.

Although this stew has much in common with the humble American beef stew, it is legitimately Japanese and wonderfully flavored with soy, ginger, mirin (the Japanese sweet cooking wine, for which sugar or honey is an adequate substitute), winter squash, and, perhaps best of all, the peel and juice of a lemon. The combination is one of simple and delicious counterpoints that make this a great stew. Ambitious cooks may want to include dashi, the quickly made stock that is one of the most fundamental flavors of Japanese cooking, but the stew is great when made with chicken stock or, for that matter, water. Other cuts of meat you can use here: short ribs (which will require longer cooking time), bone-in chicken thighs (which will cook more quickly), veal shoulder or round.

Wonderfully sweet, this side dish is the Japanese equivalent of butter-glazed carrots. Other vegetables you can prepare this way: Butternut or other winter squash or carrots.

“Don’t make a big tsimmes out of it” was a favorite expression of my mother’s, as if making a tsimmes was a big deal and therefore making a big tsimmes—well, you get the idea. Making a tsimmes—a stew of fruits and vegetables, often on the sweet side, and sometimes grains—can be a big deal, especially if you begin with a piece of meat. But as a delicious midwinter stew of dried fruits and root vegetables, served as a side dish or even a main course, it’s hardly any work at all. To make one with meat, simply add these ingredients to the Cholent recipe on page 380. Many tsimmes recipes call for cooking the fruit until it falls apart, which is all too easy to do. In this one, which has less water than most, the fruit is cooked until perfectly tender but still intact. Other vegetables you can prepare this way: vary this as you like—not only is meat common, but so are turnips, beets, apples, barley, and the small egg noodles known as farfel. The key ingredients are the dried fruit, sweet potatoes, and carrots.

Tempura is not the only batter-fried appetizer in the world; in fact, many cuisines have a similar dish, and some of these recipes follow. But tempura is very light, easy to make, and pretty much foolproof; chances are you’ll get it right even on your first try. Shrimp is the most common seafood, and probably the best, for use in tempura, but there’s no reason you couldn’t use other shellfish or even finfish. As for vegetables, it’s a matter of whatever is on hand. Harder vegetables, like winter squash and carrots, should be cut into thin slices so they become tender at about the same time they are browned. More tender vegetables—zucchini, eggplant, mushrooms, and the like—can be made larger or even, in the case of mushrooms or green beans, kept whole. Tempura, like most fried foods, must be served immediately. It will hold in a low oven for a few minutes, but as we all know it’s at its best the second it’s done. As long as you’re comfortable with your guests, serve each piece as you make it, in your kitchen. For frying, use a light, clean oil; grapeseed is probably best, but the more common (and cheaper) corn and safflower are good too. A frying or instant-read thermometer is a good idea, and temperatures of 330–350°F will work well for both vegetables and fish. If you don’t have a thermometer, put a drop of batter into the oil when you think it’s ready; it should neither sink to the bottom (too cold) nor immediately dance on the surface (too hot), but sink slightly beneath the surface and then rise to the top and skitter a bit.

Similar to Tempura (recipe follows), these are usually made only with vegetables—but a very wide assortment—and the batter is best when prepared with chickpea flour (also called besan or gram flour and available at Indian and many Asian markets and most health food stores). Traditionally, the batter also often contains anardana, a powder made from ground pomegranate seeds—if you can find some (try the same stores that have besan), add a teaspoon to the batter, along with the garam masala. Pakora batter can also be fried on its own, as a fritter; mix a medium onion, chopped, into it, and drop it by the tablespoon into the hot oil.

These sweet fritters are a cross between doughnuts and potato pancakes. That may sound strange, but, like doughnuts or churros, they make a great break fast or snack food. Buñuelos are most often made from a combination of three roots. One is yucca (also known as cassava and, confusingly enough, tapioca and manioc); it has a tough brown skin, bright white flesh, and a tough core that should be cut out before cooking. The second is malanga (also called taro), which resembles a hairy yam but has a lovely, creamy interior, sometimes streaked with purple. Finally, there’s boniato, also known as batata or Cuban sweet potato. It’s in the same family as sweet potatoes and yams (and either can be substituted here). The reddish skin encases white flesh, which is dry and has a subtle sweetness. All three of these can be found at major good supermarkets and Latin groceries, right next to one another.
