Beat the egg yolks, sugar and cornflour together until pale and combined. Combine the milk and vanilla seeds in a saucepan and bring to 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 a little then whisk again, cover with cling wrap and refrigerate.
Whip the ingredients together until soft peaks form. Refrigerate

Assemble all parts on the trifle in front of you including the jelly which should be cut up into cubes. LEAVE THE MERINGUE UNTIL LAST
Start to create irregular layers one on top of the other and in no particular order - just blissful yumminess. End with a layer of custard.
On top of the custard put blobs of meringue and then give them a blast with your blowtorch until lightly toasted. Scatter the chocolate and finish off with some cherries. Voila!
