I haven't made the recipe. I was using whisk to calculate nutritional information on recipes, making adjustments, especially when I was admin of a renal diet group. Anyway, for this recipe, the author says:
Whole psyllium husks, NOT ground psyllium husks. Psyllium is a form of fiber, that contains zero carbs. When used in keto bread recipes, gives sturdiness to the dough, without the need for any flour or grains.
