Baking 101: Flour and Sugar

No matter what you decide to bake, the dynamic duo of your baking pantry consists of flour and sugar. Each of these essentials comes in a variety of forms, and knowing which to use and how to substitute for them is essential to baking success.

Flour
Flour is the primary ingredient for most cakes, cookies, pastries, and breads. Although it is one of the most basic baking ingredients, it also can be the most confusing, because of the wide variety available on grocery store shelves. Some flours are perfect for bread baking but disastrous for piecrusts or tender pastries. What makes a flour good for one recipe and bad for another? The amount of protein it contains. The more protein a flour has, the more gluten it will produce when it's kneaded. And the more gluten you have, the less tender your baked good will be.

Gluten is the protein that forms weblike structures present in wheat and other flours. When the flour is moistened and the bread is kneaded, or when doughs and batters are mixed together, gluten forms and adds an elastic and cohesive nature to the food. This elasticity allows the dough to expand and trap the carbon dioxide, produced by the leavening, which makes the dough rise and stretch. Gluten makes it all possible!


Several different kinds of flour are available for baking; all-purpose, cake, bread, self-rising, and whole wheat flour are just a few. Become acquainted with three basic types of flour: all-purpose flour, cake flour, and bread flour.

All-purpose flour is a blend of hard and soft wheat flours. The presence of more and tougher gluten in the hard wheat results in a rather elastic product. This produces the texture you want for cakes and cookies.
Bleached and unbleached all-purpose flours can be used interchangeably, but unbleached flour has a higher nutritional value. Southern flours, such as White Lily, are made with a softer wheat, which means that they have qualities similar to cake flour. Southern flour is great for tender biscuits and piecrusts.
Cake flour is made with soft wheat, producing less gluten when mixed, so your cake will be more delicate, with a slightly crumbly texture. When purchasing cake flour, don't buy self-rising cake flour unless the recipe specifically calls for it. If you do buy it by mistake, omit the baking powder or baking soda and salt from the recipe.
You can easily substitute cake flour for all-purpose flour, or vice versa:
• If your recipe calls for cake flour and you have only all-purpose flour on hand, you can substitute 1 cup minus 2 tablespoons all-purpose flour for 1 cup of cake flour.

• If you need all-purpose flour and have only cake flour on hand, substitute 1 cup plus 2 tablespoons of cake flour for 1 cup of all-purpose flour. The texture will be different, but if you have no other choice, it's okay.

• If you have instant flour on hand, such as Wondra, combine 2 tablespoons in the cup measure, then add enough all-purpose flour to make 1 cup (which would be about 3/4 cup plus 2 tablespoons). That will also give you a flour similar to cake flour.

Bread flour has a higher gluten-forming protein content, making the dough nice and elastic. This makes it ideal for bread-making.
Don't store any of your flours in the paper sacks you buy them in. Instead, transfer them into airtight canisters and store them in a cool, dry place to make sure your flour won't absorb any odors or off-flavors. Label the containers to ensure that you can tell the difference between the different varieties (they tend to look the same out of their bags). Flour can last up to six months if stored properly in the pantry and indefinitely if stored in the freezer. If you bought the flour from a natural food store, place it in the freezer for a few days to make sure nothing will hatch.


If you use flour slowly, you can store your flour in the freezer. Double-bag the flour in sealable freezer bags and be sure to label it. Flour stored in the freezer can last for several years.

Sugar
Sugar, another basic in baking, gives tenderness and sweetness to doughs and batters. Sugar also causes browning because it caramelizes (turns brown) when heated. Sugar also is a food source for yeast, making it rise.

In baking, you need to have three different types of sugar on hand: granulated sugar, confectioners' sugar, and brown sugar (light or dark).

Granulated sugar is standard white sugar, made from either sugar cane or sugar beets, and is the most popular and readily available sweetener in baking. Superfine sugar is a form of granulated sugar that dissolves easily in liquid. You can make your own superfine sugar: Place 1 cup of granulated sugar in the blender, cover, and process for 1 minute. Let it sit for about 1 minute longer to let the "smoke" settle. This produces 1 cup of superfine sugar. Sometimes superfine sugar is used in frostings and certain cakes. It dissolves quickly, so it doesn't need much cooking time.
Confectioners' (powdered) sugar has been refined to a powder and contains a small amount of cornstarch to prevent lumping. Confectioners' sugar dissolves instantly in liquid and has a smoothness that makes it a popular choice for frostings, icings, and whipped toppings. It's also perfect for dusting cake tops and brownies. If your confectioners' sugar becomes lumpy, you can sift it.
Brown sugar, both light and dark, is a mixture of granulated sugar and molasses. Brown sugar has a deeper flavor than granulated sugar. The color of brown sugar depends on the amount of molasses mixed in; dark brown sugar has more. Light brown sugar is the most common type used in baking, but the more assertively flavored dark brown sugar is also used. Recipes specify which brown sugar to use when it makes a difference; otherwise, you can use whichever you have on hand.
• When measuring brown sugar for recipes, be sure to pack it into the measuring cup for accurate measuring.

• When exposed to air for an extended amount of time, brown sugar has a tendency to harden. If this happens to your sugar, there's a quick fix: Place the hardened brown sugar in a heatproof bowl, and place the bowl in a baking pan containing about an inch of water. Tightly cover the entire baking pan with aluminum foil and place it in a 200-degree Fahrenheit oven for 20 minutes or until softened. Use the softened brown sugar immediately, because it re-hardens when it cools. You can also use your microwave to soften brown sugar. Place the hardened sugar in a microwavable dish. Add a wedge of apple. Cover and microwave on high for 30 to 45 seconds. Let stand for about 30 seconds, then use normally.

Store all your sugars in airtight containers in a cool, dry place
