I assemble PH's Black Forest cake in a ring: cocoa cake layer followed by Kirsch flavored cream into which kirsch soaked sour cherries are embedded followed by chocolate whipped cream. I'm planning to substitute Kirsch flavored white chocolate whipped cream for the Kirsch flavored whipped cream as I am planning to freeze the cake. I am hoping that the white chocolate whipped creams will not weep as much as the gelatin enhanced Kirsch whipped cream. Any experience with these ingredients? After thawing I'll dress the edge with a thin layer of whipped cream and the top is covered with shaved chocolate as in Dorie Greenspan's book.
