WOW! WOW! WOW! Did I say Wow! This is exactly what I have been looking for, a low carb bread as I am a diabetic. I did not know that arrowroot is a carb but I calculated that 1/2c. equals 72 g. of carbohydrates roughly. So not too bad. I have enjoyed every recipe I have tried so far. I can’t tell you how happy I am that I accidentally discovered your website. Keep up the good work!! I just can’t stop making everything I see. ?
Once your yeast is proofed, add in the egg, egg whites, lightly cooled melted butter (you don't want to scramble the eggs or kill the yeast!) and vinegar. Mix with an electric mixer for a couple minutes until light and frothy. Add the flour mixture in two batches, alternating with the sour cream, and mixing until thoroughly incorporated. You want to mix thoroughly and quickly to activate the xanthan gum, though the dough will become thick as the flours absorb the moisture.
