This cake sounds like one I have made with fruit juice; some of my friends have used choc milk.
Ingredients
375g mixed fruit
400 ml fruit juice i.e. apricot nectar (can or bottle)
2 cups SR flour
Method
Soak fruit in juice for at least 6 hours
Add flour and mix well
Pour into greased and lined cake tin
Bake in moderate oven for 1 hour
Different flavours of juice give different flavour.
I got the recipe many years ago from friends and also from a patchwork web site.
Hope it is OK to add a different idea here on this post.
