Golden pear

When the pears start to ripen on our tree, I always think of the nursery rhyme we learned at school:

I had a little nut tree
Nothing would it bear
But a silver nutmeg
And a golden pear.
The king of Spain's daughter

Came to visit me
And all for the sake of
My little nut tree.

This pear is certainly golden and should be ready to eat in a few more days.  Not sure what the nursery rhyme refers to but I'll look it up when I have more time!
