Avocado Prawn Jelly Salad

Once upon a time, all housewives had jelly moulds, knew how to use aspic, polished all their cutlery once a week, went to the hairdresser at least once a fortnight and had dinner parties at least once a month. No, not Stepford. The UK. Circa 1975. Jelly was very big in the 70s. Not just sweet, but savoury and all sorts of crossovers, some of them quite vile. This, however, is just plain fun, and a little bit fabulous.
