Quince are too hard, astringent and sour to eat raw. High in pectin, they are used to make jam, jelly and quince pudding, or they may be peeled, then roasted, baked or stewed. The flesh of the fruit turns red after a long cooking time. The very strong perfume means they can be added in small quantities to apple pies and jam to enhance the flavour. Adding a diced quince to apple sauce will enhance the taste of the applesauce with the chunks of relatively firm, tart quince.
