This rustic cake is a delicious alternative to pie and uses one of the tastiest fruits of the fall harvest—cranberries. The basic recipe is very versatile and can be made with apples, pears, peaches, plums or any full-flavored, slightly acidic fruit. Just arrange the fruit in the skillet before you pour the batter over it. The cake is best served warm; if you can, put it in the oven just before you sit down to dinner.
