Kelubi
Eleiodoxa conferta · Arecaceae · also known as Asam kelubi, Asam paya, Kelubi
A sour, scaly-skinned swamp-palm fruit of the Malay Peninsula — a tart cousin of the snake fruit (salak), used as a souring agent and pickled into a tangy relish. A wild wetland fruit of Southeast Asia, sharp enough to make salak seem sweet.

The kelubi looks like a salak — same brown, scaly, snakeskin rind — but one bite tells you it’s a very different fruit. Where salak is sweet and crunchy, kelubi is fiercely, mouth-puckeringly sour, a wild swamp-palm fruit of the Malay Peninsula used not as a snack but as a souring agent.
The snake fruit’s sour cousin
Gathered in clusters from wild wetland palms, kelubi’s firm pale flesh is too tart for most to eat fresh. Instead, Malay cooks harness that sourness: pickled into the tangy relish asam kelubi eaten with rice, used like tamarind or asam gelugur to sour soups and curries, or candied with sugar to tame it into a sweet-sour treat. Vitamin-C-rich and low in sugar, it’s a genuine wild pantry ingredient, gathered from the swamps where it grows. A close relative of the snake fruit but a world apart in flavor, kelubi is a reminder that the palm family holds far more than dates and coconuts — including a scaly little swamp fruit whose whole purpose is to make other dishes tangy. For its sweet lookalike, see the salak.
