Small, underripe Asian pears — good for anything?

I have an incredibly productive Asian pear tree and this year’s crop will be insane — I thinned the fruit and have at least a hundred small (1 to 1.5″ diameter), underripe pears ready for the compost. Before I chuck them though, are they any good at this stage as a preserve of some sort? A friendly person in r/cooking suggested I ask this community.
