Sugar-apple
Annona squamosa · Annonaceae · also known as Atis, Sweetsop, Custard apple (loosely), Sitaphal
The knobby little custard grenade — scaly segments that pull apart into spoonfuls of perfumed, pear-custard sweetness around slick black seeds. The Philippines' beloved atis, best eaten with your hands.

How to select & store
Picking a ripe one
Ripe atis gives to a gentle squeeze and the scales separate slightly, showing cream-colored valleys. Hard fruit ripens at home; black cracks and fermented smell mean too late. Handle like eggs.
Storing it
Counter until soft (often just a day or two), then eat — refrigeration is a brief pause, not storage. The pulp freezes well seeded, which is the only way it travels.
Practical uses
🍽️ Culinary
- Pulled apart and eaten segment by segment — nature's hand food
- Atis shakes and ice cream where abundance allows seeding en masse
- Atemoya and cherimoya cousins in fancy fruit plates
- Taiwanese "pineapple custard apple" — a major cultivated export
🌿 Health & traditional
- Leaves used in Philippine and Indian folk practice (poultices, teas); seeds traditionally crushed as a natural head-lice remedy — never ingested
🎎 Cultural
- A Filipino backyard classic — September atis season is a childhood memory engine
- Taiwan turned atis into a flagship crop of Taitung, exporting custard apples across East Asia
Atis is engineered for eating with your hands: the knobby rind pulls apart along its scales, and each segment is a self-serving spoonful of custard with a seed for a handle. No knife, no bowl, maximum stickiness, total satisfaction — the definitive Filipino backyard fruit, gone from tree to memory in the September flood.
The custard-apple family tree
Annona squamosa is the small sweet one; soursop the big sour one; cherimoya the refined Andean one; and atemoya the deliberate hybrid (atis × cherimoya) that Taiwan grows at export scale as “pineapple custard apple.” All share the same design language: pale custard flesh, black seeds, reptilian rind.
Seeds are not food
The glossy black seeds slip out clean and were traditionally used, not eaten — crushed into a paste against head lice in Philippine and Indian folk practice. They contain annonacin and are genuinely toxic if crushed and swallowed, and dangerous to eyes. Swallowing one whole by accident is harmless; just don’t chew them, and keep the crushed-seed remedies external and historical.
