Delia Smith says this is the best chocolate dessert she's eaten in years. The recipe was given to her by the chef at the Athenaeum Hotel in Piccadilly, London. Oh, and she says it is easy to make. It can be made a few days in advance and it freezes well. You can buy liquid glucose at a chemist. This needs overnight chilling. It's very rich, so serve small portions. The system won't allow amaretti biscuits, but that's what they are.
