Inspired by recipe #378013, which I really loved, but wanted to make as sourdough. I loved the result, so I'm posting it here hoping someone else loves it as much as me! I used 2 cups of 7 grain multigrain bread flour that I found at the St. Lawrence Market in Toronto, and 2 1/2 cups of Robin Hood Best for Bread Multigrain flour (which is really white, whole wheat, cracked wheat, and ground flax.) I used 1847 Oregon Trail Sourdough which I had just gotten two days prior, but any sourdough would do! The flour can be a combination of multigrain and whole wheat or white flour, to your taste preference. If you're so inspired, top this loaf with 7 grain cereal, oats, bran. Spray the loaf with Pam or water and then sprinkle with the topping before baking.
