Flavor and texture differ with sugars

For all the different sugars out there -- white, brown, demerara, turbinado, powdered, superfine and more -- it's a little surprising that they all come from the same source: a plant.

Two plants, actually: sugar cane and sugar beets. But the sugar juice or sucrose extracted from either is, in terms of chemistry, identical.

Perhaps the marvel of sugar is that it can be transformed into various textures and flavors. And while studies say we consume too much sugar, it's difficult to imagine life without a bit of sweetening.

But which one? Here's a primer.

White sugar, also called granulated sugar, is the mainstay of baking. It's crystallized juice from sugar beets or sugar cane; some producers market the distinction, but most do not. (Brown is another matter.)

To get white sugar, sugar's natural light brown color is removed through one of several processes. The resulting white crystals are fine enough to dissolve easily, although superfine sugar is ground even more finely. That's a plus for creamy foods such as puddings or custards when you don't want a smidgen of grit.

(You can make your own superfine sugar -- also called caster sugar or baker's sugar -- by whirring the called-for amount of regular sugar in a blender.)

Brown sugar is a little more complicated. Brown sugar from sugar cane retains its residual molasses content. Brown sugar from sugar beets, however, is first refined into white sugar because beets' natural molasses is considered inferior to cane molasses. Beet sugar then is colored with molasses from cane, in varying amounts to create light brown or dark brown sugar.

If you've wondered why recipes call for brown sugar to be "firmly packed" in the measuring cup, here's why: Stickier brown sugar crystals are more likely to trap air, which can throw off a measure amount. Packing pushes out any air.

Which brings us to raw sugars, which are distinguished by their larger crystals or deeper color. The most available are demerara, turbinado and muscovado. Don't be confused into thinking that "raw" means unprocessed or more natural.

Demerara and turbinado sugars are golden and partially refined to retain some of the molasses. You can use either as table sugar, if you're seeking a slightly more molasses flavor in your coffee or on your oatmeal. They're often used as finishing sugars on cakes or muffins for a bit of crunch.

But resist using either in place of regular brown sugar because they have a different moisture content.

Muscovado has a deep molasses flavor and is an option for more savory uses such as in barbecue sauces.

Finally, there's powdered sugar, also called confectioner's sugar.

This is just regular white sugar ground into a fine powder and sifted. Most commercial sugars add a little cornstarch to keep it from clumping. This is the sugar used in finishing a baked good, either sifted over it, combined with milk and maybe a little butter for icing, or whipped into cream for a grit-free topping.
