I obtained some windfall quinces last year and took them home to make jelly. I read up in an ancient copy of Cassells Cookery that the quince seeds, when soaked overnight in water, give up about 10 times their weight in pectin. It's worth keeping the seeds in your liquid if you want jelly to set. You will have to add acid to the mix as well, as quinces do not have enough on their own.
