* Top with a second layer of Joconde (I).
* Soak with Coffee Simple Syrup (III).
* Spread on a layer of Ganache (IV).
* Top with a third layer of Joconde (I).
* Soak with Coffee Simple Syrup (III).
* Spread on a layer of Mocha Butter Cream (II). Make this very smooth and even.
* Place the Opera Torte in the refrigerator for about 15 minutes. This will allow the butter cream to firm, and make it ready for the glazing procedure.
* Working quickly, remove the Opera Torte from the refrigerator, pour the warm special opera (V) glaze on top of the firmed butter cream, and spread quickly with only a couple of swipes. The glaze begins to set very quickly, so don't continue to spread the glaze or it will become marred. Shaking the sheetpan will cause the glaze to spread evenly and result in a smooth finish look.
