green plum

This is the fruit of a small tree, Buchanania obovata,  which is native to the woodland areas of northern Australia.  It has a small green fruit which is plum-shaped, and so the name green plum. The fruits grow in clusters. The skin is thick and hard to cut. The taste has been described as similar to that of a stewed apple or pear, a little bit sweet and a little bit tart.  But it counts as a superfood because it has a lot more folate in it than most commercially available fruits.  This is the latest in a growing number of Indigenous foods which are being investigated for their commercial possibilities.
