Quince or Cydonia grow into trees, the size of apple trees. They produce large, light yellow, leathery fruits that are either pear-shaped or apple-shaped. Cydonia cannot be eaten raw, as they are very hard. They can be cooked into jelly or quince bread, also called "pork". Quinces can also be peeled and quartered, after which the core is removed and they are cut into cubes. These cubes are fried in duck fat on a pan with onions and eaten as a side dish for, for example, fried duck breast.
