Egg White Plain Loaf Bread 蛋白土司

The other day one reader left a comment in a very old post (way back 2009), said everyone should try this very soft bread. This is a bread recipe that i have totally forgotten. After i re-check back the recipe, and realized that this recipe is using egg white. Since that day i have leftover egg white, so i go ahead to modify this old recipe into plain loaf bread.
