When making smarter carb swaps in the kitchen, don't get ahead of yourself. Some swaps—like substituting whole-wheat for highly refined, all-purpose white flour—take a little more effort. While it's fine to sub in whole-wheat flour as a thickener in gravies, sauces, and soups or as a coating for oven-fried chicken, baking swaps are a different story.
Whole-grain flour contains germ and bran, which soak up liquid during baking and add weight to the dough (making it harder for it to rise on its own), creating a dense texture if you don't treat it properly.
It's made from a different strain of wheat and is lighter than traditional whole-wheat. Its flavor is also milder, making it taste more like the refined flour many of us are used to. But here's the kicker: It has basically the same nutritional value as whole-wheat flour.
Subbing white whole-wheat flour for an equal amount of all-purpose results in a denser biscuit. In our favorite CL recipe, Fluffy Buttermilk Drop Biscuits, which calls for 2 cups flour, we use 1¼ cups all-purpose and ¾ cup white whole-wheat.
