For the vanilla custard, beat the egg yolks,sugar and cornflour together until pale and combined. Combine the milk and vanilla seeds in a saucepan and bring to a simmer then turn off the heat. Do not allow it to boil over. Pour the milk over the egg mixture,whisking constantly,then return the combined mixture to the saucepan over low heat. Continue whisking for about 10 minutes,until the mixture thickens. Remove from the heat and allow to cool for about 10 minutes. Whisk again and cover the top of the custard with cling film. Cool to room temperature,then refrigerate until completely cool.
For the mascarpone cream, whip the ingredients together until soft peaks form. To make the Italian meringue,heat the sugar in a small saucepan with ½ cup of water over a medium heat until the mixture reaches 110C. Beat the egg whites in the heatproof bowl of a stand mixer until soft peaks form. When the sugar reaches 116C,pour the sugar into the egg whites in a steady stream. Continue to beat the egg whites for about 10-15 minutes,until the bowl feels completely cool.
To assemble the trifle, arrange the custard,cream,seasonal fruit (think mangoes,peaches,nectarines,cherries,strawberries,blueberries etc) and the slices of panettone in irregular layers in an attractive trifle bowl. Top with the Italian meringue and blowtorch the meringue until lightly toasted. Scatter with a few more fruits and shave over a little chocolate. Refrigerate until ready to serve.
