blended. Pour over bread and berries. Cover with foil and refrigerate several hours or overnight. Remove from refrigerator about 30 minutes before baking. Bake covered in a preheated 350 F oven for 30 minutes. Uncover and continue baking until knife inserted near the center is clean or about 20-25 minutes longer. Sprinkle remaining blueberries on top and serve with additional maple syrup if desired. Refrigerate leftovers. Yield: 10 servings.
