"Golden Spoon" and "Nance" in English, nanche fruits are produced by the tree Byrsonima crassifolia , of the Malpighia Family, native to tropical America. Notice that they are different from guavas in that their skin is shinier and their attached stems more slender. These fruits are so acid that most Northerners don't care for them. They're eaten raw and occasionally added to soups and meat stuffings.
