Fill
the apple cavities with apricots and nuts. Roll
the apples in first, follow by egg white and then the coconut. Stand
the apples in a greased baking dish and cook in the oven at 325F
(170C), for 1 hour, or until they are tender.
To
make the custard, beat the yoghurt with the eggs and sugar. Pour
into a baking dish and add the vanilla pod. Stand
the dish in a larger one with water to come half way up the sides
and cook in the oven with the apples.
