I googled keto flours and found the list of flours below. Some of the flours below are hard to come by lie hazelnut flour and sunflower flower. Chia flour looks like it may be expensive. But what about Flax meal flour or some of the others. Why did you choose carbalose flour.
Here is a list of keto flours
Almond Flour
Coconut Flour
Flax Meal
Chia Flour
Oat Fiber
Psyllium Husk Powder
hazelnut flour
sunflower meal
Carbalose acts and tastes like real flour; none of those on the list do. They don’t look, smell, feel or taste like real bread. Some of them are ok for cookies or cakes, but not yeast breads.
