Trifle - very easy

Method
Prep:30min  ›  Extra time:16hr  ›  Ready in:16hr30min 

1. Cut the Swiss roll in slices of no less than 1cm (1/2 in) thick but no greater than 2 1/2cm thick (1 in). Use a 25cm (10 in) wide by 13cm (5 in) deep bowl and place enough Swiss roll slices on the bottom to cover the base. Squash all pieces together so there are no gaps.
2. Pour some sherry on to all of the pieces of Swiss roll (enough to soak in but not too much that it's swimming in sherry). Add a layer of fruit cocktail.
3. Make the jelly according to the instructions on the packet and pour over the fruit cocktail and Swiss roll. I try to make the jelly layer the same thickness as the Swiss roll layer.
4. Place the bowl into the fridge and leave overnight to set.
5. The next day, pour on the custard and place back into the fridge for another overnight set.
6. On the day of serving, shave or grate some chocolate over the top of the custard and decorate according to taste.

Decorating the trifle

You could use hundreds and thousands, but I prefer chocolate and sliced fresh strawberries.
