That’s why cake or muffin batter is gently stirred until it’s just combined, whereas bread dough is kneaded extensively. No such thing as “all-purpose” gluten-free flour Perhaps you’ve seen, or have even bought, “all-purpose” gluten-free flour. Seems convenient, right? Unfortunately, it’s a marketing ploy, as there is simply no one-size-fits-all solution. If you want to remove wheat flour from your favorite recipe, you need to think about the role that flour is playing in the recipe in order to choose the right substitute. Remember that wheat flour contains both protein and starch. That means that the appropriate substitute will vary, because some recipes rely on one but not the other. In baking, the main role of gluten is to provide structure. Finding an alternative to replicate this structure is especially challenging because most gluten-free flours contain less protein than wheat, so they don’t do as good a job of holding the starch granules or trapping air bubbles. The proteins that they do contain are also generally less elastic than gluten. So, in as hydration. Once wet, the protein of developing more gluten and thus order to replace wheat flour with a lower- molecules link up with one another and better structure. The result is ideal protein option, like rice flour, you must form long elastic chains called gluten. for chewy artisan bread.

These gluten strands combine to form protein wheat, so it produces less a network that traps swollen starch gluten, which is perfect for tender No beans, please granules and gas bubbles produced cakes.

As a result, it doesn’t hold its shape well without support, so the pan you use to bake it has a significant impact on how it turns out. If the pan is too big, the bread will turn out flatter and denser than it should be. If you’ve ever had sandwich bread that’s not tall enough to slice for sandwiches, you know what I’m talking about. The solution is to use a pan that properly supports the dough as it’s rising during both the proofing (the period when the dough rises) and the baking stages. One option is to buy a pan specially designed for gluten-free bread. These pans have higher sides than normal bread pans to give the dough more vertical support. If you don’t have one of these pans, don’t worry. With a little extra effort and creativity you can jerry-rig a solution. Start with a 1-pound (8½" x 4½") bread pan rather than a 1½-pound (9" x 5") pan. Then use aluminum foil to form a downright … well, disgusting. So, unless greasy feel in the finished product.
