It acts as a natural binder and thickening agent, making it essential for gluten-free and low-carb recipes by enhancing texture and shelf life. Incorporating psyllium husk powder allows expert bakers to achieve improved crumb structure and a moist, tender bite while boosting the fiber content of their creations.
