How to select & store
Picking a ripe one
Buy by the bunch — plump, dusty-tan fruit that gives slightly. Fine black speckling is normal ("freckled fruit is sweet," vendors say); green tinge means sour. Camiguin and Paete fruit carry name-brand prestige.
Storing it
A few days at room temperature, up to a week refrigerated — the skin browns but flesh holds a little longer. There's no preserving tradition to speak of: lanzones season is for eating lanzones.

Lanzones is a fruit with a fan base rather than a market — grown and adored across maritime Southeast Asia, nearly unknown beyond it, because the thin skin bruises and browns within days. In the Philippines its arrival each September–October is an event: roadside stands vanish under tan clusters, prices get argued, and Camiguin island throws a full festival for it.
The pinch legend
Every Filipino child learns why lanzones is edible: the fruit was once poisonous, until a mysterious woman — in most tellings the Virgin Mary — pinched one and blessed the tree. The dark “pinch marks” on every peel are her fingerprints; the sweetness is her gift. It’s the rare origin myth you can check with your thumbnail.
Eating technique
Squeeze gently at the stem end and the leathery skin splits, releasing five segments. Most are seedless slivers of sweet-tart jelly; the occasional fat segment hides a bitter green seed — swallow-around, don’t bite. Milky sap on your fingers is normal (it’s a mahogany-family tree) and washes off. Season-mates rambutan and mangosteen share the stalls; buy all three and declare merienda.
