The fruit is knobbly and ugly, with an irregular shape and often a gray fuzz — especially when the fruit has been picked underripe. The ripest, nicest quince will have a golden tone and smooth skin like pictured directly above.
Quince may be the most difficult, yet consequently rewarding, fruit we have ever encountered. It’s completely inedible when raw, but, if you peel, hack it up, then cook it, those scents blossom into an indescribably wonderful perfume, and the fruit itself magically turns from yellowed white to a deep rosy pink.
When you stew quince in sugar and a little water or wine, it becomes not just edible but delicious — sweet, delicate, fragrant.
