Lining Charlotte Rings or Cake Rings

Sometimes a soft filling or mousse, such as Bavarian cream or other gelatin-based filling, is used in a layer cake. In these cases, it is necessary to use a ring mold to hold the filling in place until the cake is chilled enough to set the filling. These ring molds are often called charlotte rings because they are used to make charlottes, which are molded desserts made of Bavarian cream (see chapter 20). They may also be called cake rings.
