Cydonia oblonga, commonly known as quince, is a fruit-bearing tree in the Rosaceae family. It is native to Southwest Asia and Southeastern Europe. The fruit of the quince tree is typically large, yellow, and aromatic, with a hard and astringent flesh. Quinces are often used in cooking and baking, particularly in preserves, jams, and desserts. They are also valued for their high pectin content, which makes them suitable for making jellies and jams.
