Amongst boozy trifles, Sherry Trifle is the most traditional, but it's far from the only option.
This recipe makes a particularly boozy vodka and raspberry trifle.
Use of good vodka is strongly recommended: I tend to use Stolichnaya. However, if you want an extra raspberry kick and can lay hands on some, Smirnoff Raspberry Crush works very well.
Trifle's delicious, if a bit of an odd combination.
This recipebook makes a nice boozy trifle, because of the resting times, it's best if the jelly is prepared the day before - the custard and cream can be prepared on the day (but still ahead of time). It'll keep in the fridge for a few days if there's any left over.
Also known as chocolate crunch and pink custard, this was a favourite dessert/afters when I was at school. It's quick and easy to make, and tastes awesome
