Christmas Pudding Trifle

Cook Christmas Puddings according to the instructions. Drain the prunes through a sieve, reserving the syrup. Remove the stones from the prunes then roughly chop. Break the pudding into a coarse rubble, then arrange loosely at the bottom of a small, wide tumbler, wine or martini glass. Add the prunes to each one, pushing them between gaps in the pudding. Spoon over some prune syrup to moisten the pudding, then spoon over the custard. Use a balloon whisk to whip the cream until it forms soft peaks. Spoon as much or as little of it over the custard layer as you like, then finely grate a dusting of chocolate over each glass.
