Preheat the oven to 350 degrees F. Bake the Chocolate Sable dough on a small baking sheet for 5 minutes. Let cool completely. Place a Lemon Chocolate Feuilletine layer on top of sable layer. Put in the oven for 15 seconds, just to adhere the crisp layer to the sable layer. Let cool again. Spread the Apple Custard evenly over the crisp layer. Sprinkle the Apple Dice over the custard, gently smoothing it with a spatula so it lays flat in the custard. Freeze. Pour the Apple Mousse over and smooth it out. Refreeze.

In a medium bowl, cream together the butter, confectioners' sugar, brown sugar, and lemon zest. Add the lemon juice, kosher salt, and sea salt. In a small bowl, sift together the flour and cocoa powder. Add the flour mixture to the creamed butter mixture in intervals, mixing well; don't overmix or the dough will become dry. Roll out the dough between two sheets of parchment until it's 1/8-inch thick.

Strain through a fine mesh sieve into a bowl. Stir in the Apfel Korn and salt. Cool on ice, stirring often, until cold but not set.
Heat the apple puree in a saucepan. Add the bloomed gelatin and stir until dissolved. Stir in the liqueur and salt. Let cool. In a small saucepan, heat the sugar to 244 degrees F. Meanwhile, beat the egg whites to soft peaks in a bowl.

Beat until the meringue is stiff but still slightly warm. Add the meringue to the apple puree and fold in the whipped creme fraiche.
In a saucepan, heat the honey, wine, water, sugar, and vanilla bean and bring up to a boil. Strain. Let cool until just warm. Add the lemon juice and Apfel Korn to the honey mixture.
