I tried putting 1/4 cup of whole wheat flour and 1/4 cup corn meal in place of 1/2 cup of the total white flour as suggested by Bittman to make the bread a little more interesting. As you can see, the bread didn't rise very much. This was my fault as I think my yeast was too old. The resulting bread was a little dense, but still tasted very good (especially still warm!). I will definitely make this again with the same flour modifications and fresher yeast.
