Chaenomeles japonica Dwarf Quince. Fruit - raw or cooked[2, 3, 4, 11, 177, 183]. Very harsh and acid raw but fragrant when cooked, imparting a strong pleasant flavour to jams and jellies[1, 200], it is especially good cooked with apples in apple pies[K]. The fruit is apple-shaped and about 4cm in diameter. The rich aromatic juice, as tart as a lemon, is squeezed and used for culinary purposes.
