I've started a new blog called Breadmania, dedicated to the idea that you CAN make heathy great-tasting whole wheat, whole grain, and multi-grain bread in your breadmaker.
I have a Zojirushi breadmaker, and like everyone else I made several of the recipes in the instruction manual. And like everyone else, when I tried to make whole wheat bread I ended up with a bitter-tasting brick. I gave up on making whole wheat and went back to making only white bread in the breadmaker.
My wife and I have started trying to eat healthier and as a result I challenged myself to learn to make great-tasting multi-gran bread in the breadmaker. There was a lot of trial-and-error (I made a loaf once that was so bad even the birds would not eat it) but I've cracked the code and now make bread that we love. My wife recently said that the Orowheat that she used to buy now tastes like cardboard compared to my bread.
