The quince is an extremely fragrant round fruit, not unlike an apple or an orange in shape.
It has an extremely astringent and sour taste, and for years it's usually only been used to make jelly.
You probably would want to mix it with something for a bit more flavor, and use gelatin and maybe some of the other products which reduce astringency.
An old neighbor told us years and years ago, "The Polish girls used to put quinces in the drawers where they kept their underwear. The fragrance would drive the guys wild!"
Never tried that.
