A local bakery used to make a tart with a pear-flavored gel (sort of
like panna cotta) that was really delicious. What I've found online
so far is mostly pear butter, which I will try sometime now that I've
figured out that Bartletts are the ones that get so fragrant when
ripe.

I can and will experiment, but does anyone have on hand a recipe for
pear mousse or other similar dessert?
