I have just collected a couple of dozen fruits from my Japanese Quince.
Though they're as hard as bullets, most had fallen to the ground.

Will they ripen, or is that it?

How might I use such a relatively small quantity?

Hello Andy. I have no idea to the answer to your question but haven't
seen you posting for a while (you probably have posted but I have had a
new computer). Happy New Year.
