YAY! I found some Vital Wheat Gluten, by Hodgson Mill at Walmart, now I don't have to wait for it to come in stock online. (It was in the food section near the flour and yeast)
I think I feel a loaf of whole wheat bread needs to be made today!!
3/26 Update: use the gluten for the whole wheat bread and it did rise more. The texture is a bit lighter too. Flavor was the same at the first time. The top of the loaf was a bit funky, which happens sometimes with my bread machine.
