Fruit Du Jour: Noina (Custard Apple)

I saw a small woman trying to pick some strange fruit from a big tree, offered to help, got this as a reward:

This heart-shaped Thai fruit has green, bumpy skin and its creamy flesh inside tastes similar to vanilla ice cream and can be eaten with a spoon. Their peak season is from June through September. The trees need wide areas to flourish (thereby taking up a large expanse of valuable land) and and are very labor intensive as they are extremely prone to disease.
