Take half a tin of evaporated milk and put it in the fridge to cool....... empty it into a large bowl and whisk with a hand held mixer.
Melt a jelly, strawberry, rasp or blackcurrant, lemon and lime work well, in a tiny bit of water in the microwave on high for 1 minute then with the whisk going at full speed whisk the melted jelly into the evaporated milk, it will bulk up quite a bit more so make sure you have a BIG bowl....... when all the jelly has been mixed in pour into small dishes or a large dish and chill in the fridge. serve with a blob of icecream or if you feel really sinful pour double cream over the top, or whip some cream and pipe rosettes around the edge. I have done it with orange jelly in a big bowl and decorated the top with mandarin oranges and whipped cream, you can do the same with fresh strawberries if you have just a few left..... I am sure the creative among you can come up with some other idea's.
I have also used this method for a change on trifle instead if using just jelly.... it is very rich, so a little goes a long way.
