"This delicious cake combines the sweetness of orange with the tartness of fresh cranberries and sour cream. When in season, try substituting blueberries or raspberries. Bake the cake up to 1 day in advance and add icing 1 to 2 hours before serving. For testing purposes, we used a (10-cup) Cathedral Bundt pan from Nordic Ware. Dark pans will cause the cake to brown more quickly, so lower baking temperature by 25°. Greasing the pan with shortening helps ensure your cake will release all in one piece. The recipe makes 12 cups of batter; if using a 10-cup pan, bake the extra batter in a mini loafpan. For small cakes we used 2 (6-cup) Bundtlette pans from Nordic Ware and baked at 325° for 25 to 30 minutes. Prep: 30 minutes, Bake: 55 minutes...."
