I tried making my favorite banana bread recipe with Gluten-Free Pantry’s All Purpose Flour Mix. Just substitute it in a one to one ratio into a recipe, no other substitutions required. As you can see, it turned out beautifully. The recipe can be found in the Joy of Cooking, I just added a handful of chocolate chips in addition to walnuts.
The taste and texture were equally appealing. The texture was pretty close to normal flour, just a little more dense. It tasted like normal flour: the flavor was neutral, not overly rice-y or bean-y (unlike some ready-made mixes). The bread turned out slightly drier than normal, but this could be easily fixed with maybe a tablespoon of applesauce.
This probably won’t work universally, especially given that Gluten-Free Pantry has about eight other types of flour mixes for various types of baked goods. If you only bake gluten-free occasionally for a friend / family, this is a good product to keep in the pantry rather than messing with several types of flour, starches, guar gum or xanthan gum.
I have found Gluten-Free Pantry products on Amazon and at Whole Foods, as well as other specialty grocers.
