One of our favourite desserts at the moment is vanilla pudding and berries. We freeze heaps of berries during spring and summer. Usually we start with red currants, then raspberries, boysenberries, youngberries and blackberries. The strawberries are eaten fresh as they don't freeze well. If there is a glut we make jam. The blueberries are eaten straight off the bush and never make it inside the house.
Anyway, we still have a variety of frozen berries in the freezer. They are great throughout winter in all kinds of desserts, muffins, cakes, etc.
I make a thick custard. Put a layer of frozen* berries in a glass (or a bowl if you don't want to make individual portions), then pour a layer of custard, another layer of berries, etc. *There is no need to defrost the berries. Just pour the warm custard over them. They'll defrost pretty quickly and set the custard at the same time. Enjoy! :)
