I spent this past summer in Indonesia, and one of the best parts was getting to try all the wonderful tropical fruits. (I fell in love with mangosteens.) One night my host father brought home this fruit. He said it was rare to find in Java, but that his sister has a tree she brought back from Sulawesi, where it's pretty common. Problem is I can't for the life of me remember what he called it. Not sure if you can tell the scale from the picture, they're maybe a bit under 2 inches long. Anybody know what they are?
