White-Wheat Flour: This is actually 100% whole wheat flour, but it has a lighter color and milder flavor than traditional red wheat.
Gluten Option: Wheat flour naturally contains gluten, but adding a touch more helps make this dense flour more workable for a lighter result. If you can't locate gluten (sold at most grocers in the baking section), I recommend replacing 1½ to 2 cups of the wheat flour with all-purpose or bread flour.
Active Yeast: If there is any doubt that your yeast is active, proof it first in the warmed milk beverage. It should foam - if not, your yeast may be inactive - discard, get new yeast and start again. If you opt to proof, then add the yeast with the milk beverage rather than whisking into the dry ingredients. I store yeast in the freezer, which seems to preserve it well. Flat yeast will cause flat rolls!
