We tried to accommodate a wide variety of food sensitivities in our gluten-free book, but some people have asked about substitutions for what we call for in the book’s flour mixtures, and on this page, we’ll summarize swaps for flours that some of our readers don’t eat. Others may be possible, but these are the ones we’ve tested and liked.
Our Flour Mixture #1 is based on rice, sorghum, tapioca, and potato, with xanthan gum or psyllium providing structure. If you’re sensitive to the bold-faced ingredient in the list below, you can try swapping in one of the suggested alternatives. But keep in mind that if the recipe already has some of that ingredient, you may throw off the flavor or consistency. Are other substitutions possible? All we can say is that they might work, but we just haven’t tested them yet. Experiment, and adjust the liquids as needed:
White rice flour: can be replaced by brown rice flour, but you need to increase the water by 2 tablespoons per full batch of our dough recipes. We have not been able to get good results without some rice flour in the recipes.
Sorghum flour: can be replaced with oat or amaranth flour
Tapioca starch/flour: can be replaced with arrowroot starch/flour or cornstarch. However, cornstarch cannot be omitted from our brioche recipe.
Potato starch: You can try proportionally increasing the other starches/flours in the flour mixture, but you may have to adjust the water to keep the consistency at about the level that you see in our video.
Finally, some readers have asked why we didn’t base our gluten-free flour mixtures on ingredients like almond, millet, or quinoa. Though we use those in some of our recipes in the book, we’ve found that they don’t make a good yeasted bread unless they are used in relatively small amounts.
