Roll out the sugar dough into a thin sheet, freeze for 15 minutes, and repeat to achieve an even thickness.

Cool, freeze, trim, and cut the baked crust into two rectangles.

Beat room temperature egg whites to stiff peaks, gradually add granulated sugar and cream of tartar, then fold in sifted powdered sugar and orange zest.
5
Shape the meringue into slabs and bake at 195°F (90°C) for 90 minutes. Coat with a chocolate and cocoa butter mixture, refrigerate to set, and repeat to keep the meringue crispy.

Moisten the cake insert with punch, cover with vanilla mousse, top with crispy meringue, add more mousse, and seal with the pastry crust.

Repeat the assembly process with the other mold and freeze overnight.
