Santol
Sandoricum koetjape · Meliaceae · also known as Cotton fruit, Kechapi, Krathon (Thailand)
The cotton fruit — a golden tennis ball whose sour rind hides sweet, cottony white segments you suck rather than chew. A Filipino and Thai backyard classic with a serious don't-swallow-the-seed rule.

How to select & store
Picking a ripe one
Choose heavy, golden-velvet fruit with a faint peachy smell; greenish fruit is mouth-dryingly sour (which some recipes want). Big "Bangkok" santol is the eating type; small native fruit is for sinigang and salads.
Storing it
A week at room temperature — the thick rind protects it well. Refrigerated, two weeks. The pulp doesn't separate from seeds, so there's no practical frozen form; preserves are the storage tradition.
Practical uses
🍽️ Culinary
- Halved and eaten with salt, sugar, or bagoong — suck the pulp off the seeds
- Sinantolan / ginataang santol — grated rind cooked in coconut milk with chili (a Southern Luzon specialty)
- Thai som tam krathon and santol curries
- Santol marmalade and candied rind
🌿 Health & traditional
- Bark and leaves in Southeast Asian folk medicine for skin and stomach complaints
🎎 Cultural
- A schoolyard-and-backyard fruit across the Philippines — eaten green with salt by generations of kids
- The seed warning is folk-taught for real reasons: swallowed whole, the large slippery seeds have caused documented intestinal injuries — spit, always
Eating santol: what to know
What regular consumption looks like
Santol is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Santol contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

Is santol good for you?
Santol is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.
How much santol should you eat?
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Santol is two textures in one rind: slice through the golden velvet and you find firm, tart flesh (the “apple” part) wrapped around seeds wearing coats of white cotton candy — the sweet part, which you suck clean rather than chew. It’s messy, communal, unexportable, and beloved; every Filipino and Thai province has trees, vendors, and strong opinions.
Sinantolan — the fruit as ulam
Southern Luzon (Laguna, Quezon) grates the sour rind flesh, squeezes it, and simmers it in coconut milk with chilies, shrimp paste, and sometimes pork — sinantolan, a dish that treats a fruit as the vegetable main. It’s one of the clearest examples anywhere of the fruit/vegetable line being a kitchen decision, not a botanical one.
Spit the seeds — really
The one safety rule: santol seeds are large, smooth, and notorious for being swallowed with their slippery pulp — and surgical journals in the Philippines and Thailand document bowel perforations from exactly this. Adults joke about it; ER doctors don’t. Teach kids to suck and spit, and santol is nothing but pleasure — ideally with salt, calamansi, or a dab of bagoong on the sour green ones.
