Any Youse blokes ever tasted a fresh quince ?

They are huge, apple/pear like and weigh about a half a kilo
These two old trees I found in Varsseveld, in a front yard and are about 7 metres high
I picked them off the ground on the street side.  Offered to buy them but no one at home, put a couple of € in the mail slot.
Ya can't eat 'em raw, really astringent, like an unripe persimmon, but when simmered down turn pink, have a wonderful unforgettable flavour, or and texture.
I remember the smell from when a kid in Oz, 70 years or so ago, but I don't remember seeing or recognizing the fruit.
No locals here knew what it was either.......
