I tried out my new breadmaker for the first time tonight, with tasty results. Thanks for all your help! I used a recipe from the booklet that came with the machine and just skipped the dry milk. It turned out just fine. :) So, I think the moral of the post is that you don't need nonfat dry milk to make tasty homemade bread in a bread machine.
100% whole wheat bread, freshly baked.
The top didn't come out perfectly, but I think I kind of like it that way. It has character. :)
