What can I do with Quinces that isn't jam, jelly or cheese?

[ProfYaffle]

I got a stupidly large bagful from Freecycle yesterday, I'm spending today making the compulsory jelly and cheese but is there anything else I can do with them?

TIA

Quince brandy (recipe in Nigella's HTBADG)

Ooh, that sounds nice, I could add it to the 3litres of sloe gin I've got on the go!
