Strange Fruit - the Custard Fruit or Sugar Apple

Being in a sub-tropical climate means there are all sorts of nice fresh fruit to buy like pineapples, mangoes & passionsfruit to name a but a few. They all taste really delicious seeing they dont have to travel so far.
There are other more exotic and less well known fruit available and this picture shows one of them which Inge bought today - the Custard Fruit or Sugar Apple. It is fairly large with a knobbly outer shell which protects a creamy inside.

The fleshy inside contents taste like the name says - custard, only its white not yellow, and surrounds seeds which are the size of kidney beans, the flesh is quite sweet to the taste. You can eat it with a spoon. It originates from Thailand. Very exotic.
