Membrillo, also known as quince (Cydonia oblonga), is a deciduous fruit tree prized for its large, golden-yellow fruit. The fruit has a firm, aromatic flesh that becomes sweet and fragrant when cooked, commonly used to make quince jelly or paste, known as dulce de membrillo. The tree is valued for its attractive spring blossoms and glossy leaves, making it an ornamental addition to gardens. Membrillo thrives in temperate climates and is a symbol of autumn harvest.
