Monkey-puzzle Nut

This is a Monkey-puzzle nut, from our garden. It was plucked before it was fully ripe. It is resting on a plate of diameter 16cm.  It was sticky, oozing a white fluid. We kept it for a month or so, and it dried, and then I hit it quite hard with a wooden mallet and it broke in two:

 Each spike on the fruit is the tip of a separate nut:

 I cut and peeled the shell off one and ate it. Tasted unripe, woody, in the way an unripe hazelnut does.   There are lots of other fruits on the tree. We'll wait for them to fall of their own accord.
