Update 3/17/2023: I have carbalose as a convenient ingredient in my Etsy listing, but learned it may not be available outside the US. In this case, I would suggest replacing with 20% vital wheat gluten, and a blend of the other bulking fibers in the recipe (oat fiber, golden flaxseed, inulin)!

Update 3/21/2022: New low carb flour blend! I kept hearing reports that Resistant Wheat Starch 75 isn’t available for purchase. I also know that carbalose can have a bitter taste, so I wanted to balance the taste with other ingredients. Finally, I wanted to make it friendly for certain allergens: no nuts, no soy, no egg, and no dairy. Basically, it’s like a regular all purpose wheat flour with more protein and a super low net carb count. I’m making this recipe available as a digital download on Etsy, and I have another listing for a low carb challah in my shop.

Update 4/17/20: I switched over to a wheat-based low carb flour blend and am having great success with it! This blend is great for people who have no issues with gluten and are looking at Net Carbs vs. Total Carbs. I like it because it retains a nice pale color, tastes like wheat, and develops gluten with kneading very easily. The xanthan gum would provide a little more fluidity/cohesion, but I have been plenty successful without it! Try using this as a 1:1 swap with regular AP Flour.

Low Carb Wheat Flour
Yield: 300 g
Nutrition: Per 30 g serving: 100 cal, 4g net carb, 2 g fat, 15 g protein

Assuming 8 servings, the nutrition information is 12g total carbs and 8g fiber, bringing net carbs to 4g per serving. The original recipe I am riffing from is here:

Many of my recipes include the below blend of Keto Flour.  It is made from a lot of various fiber and protein powders, when combined, mimic the behaviors of starch and gluten in baking.  Sometimes I use it alone, and sometimes I build it up with other ingredients like vital wheat gluten.  It’s a wonderful tool to create baking “bulk” with very low net carbohydrate content. Make a scaled-up batch and store in an airtight container.
