Here we are in the dog days of summer and I’ve been thinking about baking. In the past year, I’ve received more than the usual number of inquiries asking me how much the gluten-free flours that I use in my gluten-free flour mixes actually weigh. And so I’m finally going to put the weights, along with an explanation, here as a blog post for anyone who’s interested (I had already posted most of them in a less detailed response to a question on the Guide to Flour Mix page). Years ago, I weighed each of the flours and the mixes myself (I weighed each of them between 10 and 15 times) and also asked more than ten of my regular field testers to do it in their own kitchens at least five times. In many cases, the weights were identical. If they were weren’t identical, and there wasn’t a huge difference (there never was), I took the average.
It is important for you to realize that a fraction of an ounce or gram is not going make or break a recipe. I still use measuring cups to measure all my flour because for me, it is faster and easier and it works every time. But if you want to weigh the flour to make my mixes, here is what you’ll need to know.
BROWN RICE FLOUR MIX
Brown rice flour (extra finely ground) 2 cups
Potato starch (not potato flour) 2/3 cup
Tapioca flour (also called tapioca starch) 1/3 cup
Authentic Foods Brown rice flour 1 cup = 4 ounces (113 grams)
Potato starch 1 cup = 6 ounces (170 grams
Tapioca flour 1 cup = 4 ounces (113 grams)
1 cup Brown Rice Flour Mix made with Authentic Foods = 4.4 ounces (125 grams)
BREAD FLOUR MIX
Millet flour 2 cups
Sorghum flour 1 cup
Potato starch (not potato flour) 1 cup
Tapioca flour (also called tapioca starch) 1 cup
Corn starch 1 cup
Millet Flour 1 cup = 4.75 ounces (135 grams)
Sorghum Flour 1 cup = 4.5 ounces (128 grams)
Potato starch 1 cup = 6 ounces (170 grams)
Tapioca Flour 1 cup = 4 ounces (113 grams)
Corn Starch 1 cup = 4.75 ounces (135 grams)
1 cup Bread Flour Mix is between 4.25 (121 grams) and 4.5 ounces (128 grams). The difference between the two numbers amounts to about one tablespoon of the flour mix, and is dependant upon which brand of millet and sorghum you use. Also, if you add up the total weight for each flour to make 6 cups of the mix and divide by 6, you will get 4.8 ounces (136 grams) per cup. The difference between that number and my designation of 4.25 and 4.5 as total weight per cup of the mix is do to aeration of the flour mix before measuring (see the How to Measure and Mix Gluten-Free Flours section below). The Bread Flour Mix is half whole grain and half starch, and so it takes in more air during aeration than the Brown Rice Flour Mix, which is two-thirds whole grain.
How to Measure and Mix Gluten-Free Flours
Using Volume Measure: Flour scooping versus spooning
Everyone measures flour a difference way: some people scoop, some sift, some spoon, and some dump it into the cup. But the amount of flour you end up with in that one cup measure can vary depending on the method you use, and it can vary a lot – by one tablespoon, more or less. So I have tried to narrow the variables that can go wrong. By specifying a specific method and describing it to the best of my abilities, I am trying to make sure that your cupcake or muffin comes out as well the ones I make in my own kitchen. I suggest you spoon flour into the measuring cup. If you scoop your flour, you may inadvertently add 1 tablespoon or more flour and make a heavier, denser cupcake. Perhaps you might not notice it unless you test side my side- as I always do. But along with great taste, texture and appearance, my goal also includes consistency: you should be able to make the best possible version of the recipe every single time.
To measure flour for making flour mixes: use a soup spoon to spoon each flour from the package into the measuring cup, or pour flour from the package into the measuring cup (my favorite method), then use a knife (or even the handle of the spoon) to level the top. Do not scoop gluten-free flours out of the package with the measuring cup. Empty the measured flour into a plastic container large enough to leave four to five inches from top. Shake the container vigorously to mix the flours. I usually make 12 cups of brown rice flour mix at a time and store and shake it in a 21 cup container.
To measure flour for use in recipes: Shake container vigorously to mix and aerate the flours (shake and bake). Use a soup spoon to spoon the flour from container into the measuring cup, then use a knife (or handle of the spoon) to level the top. Do not scoop gluten-free flours out of the package with the measuring cup.
Using Weight Measurements:
To measure flour for making flour mixes: Use the weights given above to make desired amount of Brown Rice Flour Mix or Bread Flour Mix. Empty the measured flour into a container large enough to leave four to five inches from top. Shake the container vigorously to mix the flours.
To measure flour for use in recipes: Use weight measurement below or volume measurement from Using Volume Measure – To measure flour for use in recipes just above.
