Pouteria Caimito "Abiu" seedling: Emperor's fruit ... rare from the Amazon.

An abiu fruit has a roundish oval shape, about the size of a peach, with a pointy end. In some varieties, the pointy end is larger with a small bulbous protrusion. The skin of the abiu fruit is smooth and shiny, dark green when it is immature, and turns into a brilliant golden yellow color when the fruit is ripe and ready to be picked. Abiu is usually eaten fresh. You just cut the fruit in half lengthwise and use a spoon to scoop out the soft flesh inside. A ripe abiu has a unique taste. The creamy white flesh is extremely delicate, lightly sweet, with a strong hint of caramel and vanilla. Some people describe the flavor as similar to a crème caramel flan!
