4 lg. egg yolks
3 tablespoons cornstarch
1 1/2 cups milk
2 teaspoons vanilla
3 tablespoons unsalted butter, softened
9 ounces white chocolate, chopped
1 cup heavy cream
drained, reserving ⅓ of the syrup
1 env. unflavored gelatin
3 tablespoons framboise
1/2 cup heavy cream
2 1/2 cups fresh raspberries
White chocolate, room temp., shaved into curls
chilled fresh mint sprigs
White chocolate genoise (recipe follows), cut horizontally into 3 layers 1/4 cup framboise for brushing the cake layers.
Make the white chocolate mousse: In a bowl whisk together well the yolks, the sugar and a pinch of salt. Add the cornstarch, sifted and whisk the mixture until it is just combined. Add the milk, scalded, in a stream, whisking transfer the mixture to a heavy saucepan, and boil it whisking, for 1 minute or until it is very thick and smooth. Strain the pastry cream through a fine sieve into a bowl, stir in the vanilla and the butter and chill the pastry cream, its surface covered with plastic wrap, until it is
Line the sides of an oiled 9 1/2 inch springform pan as smoothly as possible with pieces of plastic wrap (the plastic wrap prevents the filling from discoloring and makes unmolding the cake easier), letting the excess hang over the side, and put an 8 inch cardboard round in the bottom of the pan. Invert the top layer of the genoise onto the round, brush the cake with some of the mousse (about 2 cups). Invert the middle layer of the genoise onto the mousse, brush it with some of the remaining framboise, and chill the cake and the remaining white chocolate mousse while preparing the raspberry mousse.
Make the raspberry mousse: In a blender or food processor puree the raspberries with the reserved syrup and strain the puree through a fine sieve set over a metal bowl, pressing hard on the solids. In a small saucepan sprinkle the gelatin over the framboise and let it soften for 1 minute. Heat the mixture over moderately low heat, stirring, until the gelatin is dissolved and whisk it into the puree. Whisk the reserved pastry cream into the raspberry mixture,
Spread about 1 cup of the raspberry mousse evenly over the middle layer of genoise in the pan, arrange some of the raspberries neatly around the edge of the pan, and continue to arrange the raspberries in concentric circles until the surface of the mousse is covered. Spread the remaining raspberry mousse over the raspberries, invert the third layer of genoise onto the mousse, and brush it with the remaining framboise. Spread the remaining white chocolate mousse over the genoise (the pan will be completely full) and chill the cake, its surface covered with a sheet of wax paper, for at least 6 hours or overnight. Remove the side of the pan, peel the plastic wrap carefully from the side of the cake, and transfer the cake with a spatula to a plate.
