Many years ago a lady friend sent me to buy trifle sponges - I got chocolate ones by mistake and was accused of trying to sabotage her cooking...

However, many years later, when Rowntree's brought out a Black Cherry flavour jelly, memories of the mistake sparked off some ideas - tinned cherries, whipped cream and kirsch were also involved. That flavour is no longer obtainable, so I now use red grape juice + gelatine. It's become one of my signature recipes.
