Soursop vs Durian: What's the Difference?

Short answer: Soursop and durian look alike from outside — large green fruit with a spiky rind — but they're unrelated and taste nothing alike. Soursop has soft, spineless prickles and white, fibrous flesh that's tangy-sweet like citrusy pineapple-cream, with a mild smell. Durian has hard, sharp spikes and dense, custardy yellow flesh that's intensely rich and sweet with a famously strong, pungent aroma. Soursop is refreshing and sour; durian is heavy, savoury-sweet and divisive.

From a distance you might mix them up — both are large, green and spiky — but soursop and durian are unrelated and could hardly differ more inside. Soursop has soft, bendable spines and white, fibrous flesh that tastes tangy-sweet, like pineapple and citrus folded into cream, with only a mild scent. Durian bristles with hard, sharp spikes and hides dense, custardy yellow flesh that’s intensely rich and sweet — and carries the powerful, pungent aroma it’s famous (and sometimes banned) for.

So the skin fools you; the eating tells the truth. Reach for soursop when you want something refreshing and sour, often blended into juices and ice cream. Reach for durian — if you dare — for a heavy, savoury-sweet experience that fans adore and others flee.

Frequently asked questions

Are soursop and durian related?

No. They just share a green, spiky exterior. Soursop is an Annona (custard-apple family); durian is in the mallow family. Their flesh, flavour and smell are completely different.

Does soursop smell as strong as durian?

Not at all. Soursop has a mild, pleasant fragrance. Durian is notorious for its powerful, pungent aroma — strong enough to be banned in some hotels and transport — which soursop never has.

Which is sweeter, soursop or durian?

Durian is far sweeter and richer, with dense custardy flesh. Soursop is tangy and refreshing, balancing sweetness with a distinct citrus-like sourness.
