Let joy be unconfined. This is one of the most irresistible puddings I think I have ever made, and I did it by no more than some fruitful scimmaging about my cupboards. I long for it almost constantly, and it is not good that it is so easy to make, not good at all. If you don't run to Frangelico yourself - and there is no reason why you should - then simply replace this hazelnut sticky liqueur with some rum.
