A dull mystery I solved recently:
My neighbor lets me (and my kids) pick her pear tree every year as she doesn't care for pears. The first time I picked it - maybe 5 years ago? - I noticed that the lowest pears on the tree were a lot worse than the other pears: very, very hard, and sourly astringent if you bite them. Also, they're fuzzy on the skin. But the other pears on the tree are perfect, so my kids and I just ignored the "fuzzy pears" and picked the good ones. Well, each year, more and more of the tree is bearing "fuzzy pears." This year, I cut one up and noticed the seed pattern is quite different from the seed pattern in the pears.
Then it finally clicked.
Years ago in Chile, a farmer gave me a slice of fruit called a membrillo. It was sour and borderline inedible, but the farmer said it made good jam ("dulce de membrillo"). I looked it up, and it turns out that membrillo in English is quince, a close relative of pear, and around here (Utah, USA), pear tree starts are often grafted onto quince root stock because it's a hardy and disease-resistent tree.
My neighbor's tree is gradually being taken over by the quince root stock. I guess I'll have to learn how to make dulce de membrillo. (pictured: neighbor's tree, pear and quince from that tree, banana from a different tree, I'm sure)
