How to select & store
Picking a ripe one
Choose fruit whose rough skin has flushed orange and gives slightly with a sweet-sour smell; green fruit is unripe and heavily latexy. The small round fruit is often gathered from the forest floor.
Storing it
A few days once ripe — perishable and latex-prone. Eaten fresh soon after opening; the seeds are saved and roasted.

The jackfruit has many wild relatives, and the monkey jack is one of the liveliest — a small, round, rough-skinned forest fruit that ripens orange and hides sweet-sour, deep-orange flesh. Sharper and far smaller than its giant cousin, it’s a fruit of the Southeast Asian jungle, prized by monkeys and foragers alike.
A tangy fruit of the forest floor
Where jackfruit is mild and honey-sweet, the monkey jack brings a bright sweet-sour tang, its juicy orange flesh clustered around numerous seeds. Those seeds are a bonus crop, boiled or roasted like little chestnuts, so a single fruit offers two foods. It runs with milky latex like all Artocarpus, and is mostly gathered wild — from the forest floor or low branches — though villages sometimes plant it for fruit, timber, and dye. Kin to the jackfruit, the marang, and the miniature kwai muk, the monkey jack is the tangy, wild-hearted member of the clan — the one you’re more likely to share with a monkey than to find in a market.
