Torta di Mele della Nonna (Italian Grandmother's Apple Cake) A grandmother's apple cake is mostly apple. Just enough batter holds the wedges together, so each slice looks slightly precarious and tastes of fruit rather than sponge. Two pounds of apple meet seven ounces of flour, and that ratio is the whole recipe. It is made in one bowl, with a hand whisk and melted butter, and it is better on the second day than on the first. Yield: 8 servings from one 9 inch cake. Prep: 30 m
