I quite like trifle, but it's only close family so I think I can risk something different. How about a Caribbean inspired one (with a little bit of Italy):
Panetone
Prunes and raisins soaked in rum
Custard
Bananas and caramel sauce
Cream ( caramel peanuts on the top for a bit of crunch?)
I know the prunes may be a bit odd but a friend made a chocolate cake with prunes soaked in brandy and it was heavenly.
Do I have a future career inventing recipes? Votes please on whether this sounds worth the risk!
