The Kaffir plum tree has a broad shady canopy and can reach heights of 15 meters. It has dark green sickle-shaped leaves that have a glossy appearance. An odd red leaf may be scattered throughout the foliage, which is key to its identification. White blossoms give way to loose clusters of oblong fruits. They are 3 cm long and first appear green but become bright red when ripe. Their interior resembles that of a mango with peachy-orange flesh surrounding a large seed. Fruit has a soft velvety texture and a tart acidity balanced by creamy notes of mango and passion fruit. While there is a small fruit to seed ratio, the skin easily comes away from the flesh, making for quick preparation.
Seasons/Availability Kaffir plums ripen through the summer and are forgeable in autumn.
