I used the powder for a pizza crust. Was pretty yummo!! It can also be incorporated almost in anything you drink - water, shakes, smoothies, etc. I got mine from Whole Foods and Sprouts too!
It can totally be used in cooking. It makes “bread” recipes mimick the bready texture. What you don’t want to use is the medicinal psyllium husk (Metamucil). Make sure you’re getting the one from the food section as indicated above. :]
