Have just picked 15 quinces but will have to freeze them, leave them to soften, partly cook them or grate them, as they are so hard. Have made quince jam/butter and they are nice in an apple pike. Any other successes that you have had using them?
I haven't made it myself, but the cheese shop I use sells Membrillo (I think it's called), which is blocks of quince paste, and you have it with cheese. It's yummy.
Don't cut them on a plastic chopping board. Mine still bears the brown stain of quinces from five years ago, in spite of many scrubbings. What I do with them is to slice them and dry the slices which look pretty in pot-pourri
