Sour plum
Ximenia caffra · Ximeniaceae · also known as Large sourplum, Wild plum, Umthunduluka, Mutshato
A bright red-to-orange African fruit as sharply sour as its name promises — thin-fleshed, tart, and refreshing, gathered from thorny savanna shrubs and made into juices, jams, and drinks, with a prized oil pressed from its seed.

How to select & store
Picking a ripe one
Choose fully red-to-orange, slightly soft fruit for the best (still tart) flavor; firmer fruit is intensely sour. Gathered from thorny bush shrubs in the wild.
Storing it
A few days once ripe — perishable. Usually made into juice, jam, or cordial promptly, which keeps far longer than the fresh fruit.

Eating sour plum: what to know
What regular consumption looks like
Sour plum is a nutritious everyday fruit, best enjoyed as part of a varied diet. It is a good source of vitamin C (about 45 mg per 100 g), supporting immune function and helping the body absorb iron from plant foods.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Sour plum contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The sour plum makes no false promises — this bright red-to-orange African fruit is as sharply, refreshingly tart as its name says. Gathered from thorny savanna shrubs across southern and eastern Africa, its thin juicy flesh is a puckering, vitamin-C-rich thirst-quencher on a hot bush day.
Sour fruit, prized oil
Too tart for most as a steady snack, the sour plum shines processed: juices, cordials, and jams that harness its bright acidity, and a role as a natural souring agent. But like its famous savanna neighbor the marula, it gives a second gift — the kernel inside its large seed is pressed for Ximenia oil, traditionally used on skin and hair and now a sought-after ingredient in the natural-cosmetics trade. So a single hardy bush fruit quenches thirst, sharpens preserves, and moisturizes skin, all while its leaves and roots feed into southern African traditional medicine. Bright, sour, and useful from flesh to seed, it’s a small red jewel of the African bush. For fellow hardy savanna fruits, see the monkey orange and kei apple.
