This Rustic Sourdough Cinnamon Raisin Struan, is made with cooked brown rice, coarse cornmeal, rolled oats, oat bran and a mix of raisins and cranberries. To give it an over-the-top flavor, the dough is rolled out, brushed with melted butter and sprinkled with cinnamon sugar. And for the finishing touches, the top of the loaf is brushed with melted butter and sprinkled with cinnamon sugar.
