A fruit I had never seen before, that was also a green color, was introduced to me recently; but this fruit is ripe:
In Khmer it's called "pry tee-ahp." In Spanish it's "cherimoya" and in English I've heard it called custard apple or anona.
You peel off the bumpy green outside. It's thick and dry, so it peels off easily from the grape-like consistency of the interior.
Inside, the white part is divided into sections. Each section has a big, shiny, black seed inside.
The white part is delicious! It has a peachy, pear-like flavor. Compared to its ugly exterior, it is surprisingly nice!
