The other reason is I like bread, but would rather enjoy bread without preservatives in it. I don't know that I can detect them by taste, but the breads I've presented here are so delicious I don't think I'll ever go back to "store bought" again. It just doesn't measure up.
The only real problem with "home-made" bread is its propensity to spoil. Since we all have refrigerators that's not a problem either.
