Eric,
At one time, trifle was made for special occasions like Christmas, birthdays etc, many years ago.
Nowadays you just pick up ready made gloop off the supermarket shelves, that taste of absolutely nothing.
These are very easily made ones that come in a small box called 'Birds' trifle, and come in different flavours, where you (shocks and wonderment!!) actually make it yourself from the enclosed ingredients.
Mal makes me one every couple of weeks, when I have behaved myself and been a good boy.
If the lads in the UK really want to remember what they were like, they should get their partners better trained, and get them to make one occasionally.
