There’s a great episode of The Simpsons where Bart gets adopted by next-door do-gooder Ned Flanders. It’s all funny, but the part which stuck in my mind was a sequence where Bart is hiding in a tree (don’t ask) and Ned makes him a late-night hot chocolate. He adds whipped cream, grates over chocolate, pops in a fudge-stick and puts a marshmallow on the end, which he toasts with a blow-torch. I have tried many times to recreate this screen delicacy and never quite managed to pull it off – but that’s no reason to stop trying, right?
