We tried this recipe because I was craving having blueberry streusel scones (# 244646) again. However, I am trying to cut down on my saturated fat and cholesterol, so we looked for something to fill that baked goods craving without blowing my daily saturated fat limit, and Alton Brown is often a decent place to start. We used whole wheat pastry flour with some flax meal thrown in for good measure, frozen blueberries allowed to thaw slightly, and a silicon muffin tin. They were somehow dense and light at the same time, and had an interesting buttermilk note (we assume from the yogurt). Also, Alton says muffins are really more like pancakes than cupcakes!
