Nut

GOOD TO KNOW Although this version of a classic Thai noodle dish is vegetarian, we’ve added a little optional protein in the form of scrambled egg. You could add thinly sliced poached chicken breast instead; add chicken to the skillet in step 3, tossing to coat with sauce.

SMART SUBSTITUTION This lighter interpretation of a traditional Waldorf salad replaces the sweet mayonnaise dressing with one made from reduced-fat sour cream, white-wine vinegar, and just a hint of sugar.

GOOD TO KNOW Quinoa—a nutritional powerhouse that’s also an excellent source of protein—stars in this vegetarian main; chopped walnuts complement quinoa’s nutty taste. Choose short, squat bell peppers that will stand upright easily.

WHY IT’S LIGHT Each serving of this stir-fry has only one teaspoon oil and a tablespoon of roasted peanuts. Lime juice and fresh basil added at the end perk up the dish, so it tastes just as good as (or even better than) more traditional versions.

GOOD TO KNOW Succulent yet lean, scallops can be seared on the stove without adding much—if any—butter or oil. Be sure to heat the skillet until very hot before adding the scallops, and wait until a crust forms before turning them, to prevent tearing. Browned butter (beurre noisette in French) and hazelnuts add richness, without tipping the scales.

WHY IT’S LIGHT Since they contain no butter or oil, these crunchy, nut-studded treats are significantly lower in fat than other cookies. Whole-wheat flour gives the wholesome biscotti extra fiber.

Although the origins of spritz cookies are fuzzy—some say they come from Scandinavia, while others cite Germany—I'm inclined to believe it's the latter, because spritzen means to squirt in German, which is how these cookies are formed: The dough is squirted from a cookie press. You can make any shape you want, but we love these old-fashioned washboard strips. If the idea of yet another piece of kitchen equipment deters you, rest assured these cookies are so delicious, you'll be baking them more than once a year. A cookie press is not expensive and with all the different shapes you can make from the dough, it will more than pay for itself in fun and entertainment over the years for the child in all of us.

The Linzer cookie, thought to have originated in the city of Linz, is based on the Linzertorte, one of the most famous and beloved confections in Austria. The cookies are like mini versions of the torte, which consists of a buttery dough, rich with ground almonds or hazelnuts, spread with jam—usually raspberry or apricot these days, but originally with black or red currant jam or jelly—and then topped with a lattice of more dough before baking. You don't see Linzertortes often on this side of the Atlantic because the Linzer cookie is so much easier to make and delivers the same wonderful interplay of flavors. With its snowy dusting of confectioners' sugar and glistening red raspberry jam filling, which peeks out from the center of the sandwich cookie, it definitely screams "holiday."

Pesto is a traditional pasta sauce, but it is also a delicious sauce for grilled vegetables and chicken, salads, and pizzas, and a perfect final flavoring to a bean and vegetable soup.

Serve these nuts as candy, use them to garnish a cake, or fold into homemade ice cream.

This is a wonderful side dish for pan-fried fish.

Any variety or combination of summer squash will do for this recipe. Use more than one color for a more vibrant dish.

In Italian, biscotti means “twice-cooked.” Biscotti are baked first in long loaves, then sliced into thick cookies, and baked again until lightly toasted. The cookies are crisp and dry, and store well; and I like the fact that they are not extremely sweet. Various ingredients such as nuts, chocolate, spices, liquor, and dried fruits are added for flavor. I make biscotti flavored with lightly toasted almonds and aniseed. They go equally well with a cup of coffee or tea or a glass of wine. The biscotti recipe I use most often has no butter. Eggs and sugar are beaten together until they increase in volume, turn light in color, and form a ribbon when you lift up the whisk or beaters. This means the mixture will fall back onto itself slowly and thickly in a ribbon-like pattern. When the eggs are warm it will take about 3 or 4 minutes to beat the eggs to this point; when they are cold, it can take up to 10 minutes. If you have forgotten to take the eggs out of the refrigerator in advance, warm them for a few minutes in their shells in a bowl of almost-hot water. Air trapped in the beaten egg mixture lightens the texture of biscotti. Be careful to stir in the flour only until it is just incorporated, and then gently fold in the other ingredients so as not to deflate the eggs. Form the dough into long loaves on a baking sheet lined with parchment paper. The dough will be very wet and sticky. Wet your hands before touching it to keep them from sticking. Use a spoon and your hands to smooth the logs. Bake them until golden and set. When removed from the oven, the loaves are quite delicate until cooled. Carefully pull the whole sheet of paper with the loaves right onto a cooling rack. When cool, slice the loaves with a long serrated bread knife (on a diagonal, for longer cookies). Spread the cookies out on the baking sheet and bake again until golden and toasted. They will keep for up to a month in an airtight container.

Crisps and cobblers are humble desserts, not too sweet, and full of flavor. A deep layer of fruit is baked under a crunchy topping or cream biscuits, much like a deep-dish pie with a top crust. Every season has fruit to offer: apples and pears in fall and winter, rhubarb and strawberries in the spring, and all the stone fruits and berries of summer. A crisp topping is a coarse mixture of flour, brown sugar, nuts, and spices, with butter worked into the flour mixture just until it’s crumbly. Crisp topping is as easy to make in large batches as it is in small batches, and it freezes very well for up to 2 months. It is a convenient staple to have in the freezer for a quick dessert for an unexpected occasion. Topped with biscuits, cobblers are less sweet than crisps and best made with juicy fruits. I make simple cream biscuits out of flour and butter worked together, leavened with a little baking powder, and moistened with heavy cream. The dough is rolled out on the thick side and cut into shapes. Once cut, the biscuits can be held in the refrigerator for an hour or two before baking. Crisps and cobblers work best when the fruit is piled high. For both desserts the fruit is cut into bite-size pieces (1/3-inch-thick slices or 1-inch cubes) and, like fruit pie fillings, tossed with a little flour and a little sugar. Use less sugar for crisp fillings because the crisp topping is so sweet. Tart rhubarb needs quite a bit of sugar, apples need less, and sweet fruits such as peaches need almost none at all. Taste the fruit while you are cutting it and again after it is sugared; you can always add more. The flour thickens the juices that would otherwise be too soupy. It doesn’t take much, a tablespoon or two at the most. A crisp or cobbler is served straight from the dish it has been baked in, so choose an attractive one. Ceramic dishes are best, as metal pans will react with the acid of the fruit. The dish needs to be about 3 inches deep to accommodate a generous layer of fruit. Place the dish on a baking sheet to catch any overflowing juices. Cook until the crisp is dark golden brown and the fruit is bubbling up on the sides; a cobbler’s biscuits should be cooked through and golden. If the crisp topping is browning before the fruit is done, place a piece of foil over the top to protect it. Lift off the foil for the last few minutes to recrisp the topping. Serve right away or put back in the oven to warm for a few minutes before serving. Cobblers and crisps are delicious on their own but are even better served with a little cold heavy cream or whipped cream.
