To make a spider web design, make a thin white icing (powdered sugar and eggwhite mixed to the consistency of ehavy cream) and, starting at center of cheesecake, pipe a continuous spiral to the outer edge of the cake (practice on the counter first). Pull a knife point from the center out through the white lines, dividing the cake into sixths. Then reverse the procedure between the lines, pulling the knife from the outer edge to the center of the cake. Refrigerate until served.
