Angel food cake baked from a box mix gets rolled while still warm into a kitchen towel, cooled completely, then unrolled and spread with side-by-side stripes of softened raspberry, orange, and lime sherbet — one and a half cups of each. Re-rolled and wrapped tightly, it freezes for several hours until firm enough to slice cleanly into 16 servings. The full process takes about 8 and a half hours, nearly all of it freezing time. Cut with a serrated knife in one confident stroke to keep the sherbet stripes intact in each slice.
