BBA White Bread adapted for Bread Machine w/ Tangzhong Roux

I adapted the Peter Reinhart's "White Bread variation 2" recipe from The Bread Baker's Apprentice for the bread machine. I also adapted the recipe to make a Light Whole-Wheat loaf.

In addition, I added a Tangzhong roux to make an even lighter loaf. This makes the best, lightest sandwich bread and the best white bread and light wheat breads that I have seen come out of a bread machine.
