I have tried dried whey but there are other protein powders I like better in yeast breads, rolls, etc. I used the following until I used it up, then tried a few more products designed for smoothies but work great in baked goods. I decided that I like the texture and the flavor of the breads and rolls made with this product better than the others. I recently ordered it again.
A year ago I got a container of Octonuts Almond Protein powder, a California product.
