A decade ago, gluten-free all-purpose flours for baking were difficult to find in supermarkets. That meant some home bakers who have celiac disease or gluten intolerance spent a lot of time fiddling with starches and alternative flours to create a worthy substitute.
Things have changed.
Gluten-free all-purpose flours have joined an array of gluten-free baking products. They offer home bakers a chance to prepare some favorite recipes free of gluten, a stretchy protein that captures gas bubbles made by leavening agents used to increase a baked good’s volume.
There are about two dozen gluten-free all-purpose flours these days, both well-known brands and smaller independents. They rely on a variety of flours (from grains, legumes, beans) and starches (corn, potato, tapioca, arrowroot) to create a flour’s powdery element. To give baked goods the structure and texture usually provided by gluten, most use xanthan gum or guar gum, both commonly used food additives.

We decided to test a half dozen of these flours to see how they perform in a standard baked good. We chose a basic plain muffin recipe, preparing a control batch with standard all-purpose flour, then baked batches with the gluten-free flours. (The flours we tested can be used cup-for-cup in recipes.) We did not add any nuts or fruit, so we wouldn’t be distracted from the taste and texture of the muffins. To those with no gum element (Bob’s Red Mill, King Arthur), we added xanthan gum.
Bob’s Red Mill, Cup4Cup and Namaste produced a moist, somewhat typical muffin batter. The others created almost sticky, pastelike batters. Yet each made the recipe’s dozen muffins, with all but Betty Crocker and Glutino rising to a height of 2 inches plus.
Our tasters (all bakers, some with gluten issues) enjoyed the good flavor and decent texture of each. Rated on a scale of 1-9, they all fell in the average range — with a few quibbles noted in the chart.
Which gluten-free all-purpose flour you choose, from those tested here as well as others on the market, will depend on several factors: your budget (prices for the ones tested ranged from 21 to 35 cents per ounce), shopping criteria (no GMO ingredients, kosher), personal preferences (you like the nutty flavor of brown rice) and dietary considerations (you want the extra protein in Bob’s Red Mill; you can’t have dairy or soy or those gums, xanthan and guar).
When shopping, do not confuse these all-purpose flours with, say, bread mixes (which may have added yeast) or baking mixes (which may have added baking powder or baking soda). Most of these are available nationally, have a store locater on their website or can be purchased online.
