Homemade English Muffins! Oh boy! Never again be fobbed off with those little white sponges sold in grocery stores. I have called for whole wheat flour because that is what I use, but you can certainly use all or part hard unbleached (white) flour. The ascorbic acid (Vitamin C powder) is available in bulk food stores, but you will not need it unless your flour is organic, and does not have dough conditioners added. Don't be put off by the length of the instructions, these are really quite easy. You can even make the dough in your bread machine.
