I use a bread machine.
These bad boys have been around for a while now and can be picked up cheap at garage sales or thrift stores. Usually they can be had for $10 or less when bought used.
So I bought a backup at a thrift store for $5. It looked brand new.
This machine, it turns out, is a major step up. It has a one-hour cooking feature! No kidding. I dump in the ingredients, hit the buttons, listen to it whir, smell that yummy fresh bread baking, and then we can eat it only an hour later. (Well, really it's supposed to cool for 15 minutes after baking before slicing but sometimes I cheat there, too. Can you blame me?)
The secret to making whole wheat bread is to use a couple different types of flour. A regular whole wheat flour and a higher gluten whole wheat flour (I use "Wheat Montana's Prairie Gold").
The ingredients must go into the bread machine in a certain order. The wet ingredients first (water, oil) followed by the dry ingredients (flour, salt, sugar), and last the yeast.
Then push a button and say a quick prayer. With any luck, you'll end up with a beautiful, delicious loaf.
