Select 6 whiskey glasses (preferably with a wide base)
Place a slice of the jam roll in the base of each whiskey glass
Sprinkle Marsala over each slice of roll
Make up Jelly using only half the amount of water listed on the packet, and while warm, pour in each glass to cover the jam roll
Place the glasses in the refrigerator to set.
Either make up a small amount (500ml) or open a carton of custard.
Pour over the set jelly in the glasses till half full and put back in the fridge.
When the remainder of the jelly is cold (not set), gently pour a layer in each glass over the custard (pour onto a spoon is best) and place back in the fridge to set.
Once set - place a layer of whipped cream over the jelly and decorate with washed and quartered strawberries and blueberries.
A light dusting of icing sugar on top also looks nice!
Serve to each guest chilled - with a long spoon.
Notes & Tips
Make sure the custard and the jelly is cool when pouring in, and if the custard is not set - pour in the jelly very slowly (one in the picture was poured too quickly as you can see - no layering effect)
