A frozen dessert consisting of layers of ice cream or sherbet. The ice cream is softened and spread, one layer at a time, in a mold. Each layer is hardened before the next one is added. The center of a bombe is often custard laced with fruit. After it's frozen solid, the bombe is unmolded and often served with a dessert sauce. The original bombe molds were spherical; however, any shape mold may be used today.
