Sangkaya Fak Thong
สังขยาฟักทอง
Sangkaya Fak Thong is Thai pumpkin custard — a whole kabocha pumpkin steamed with a coconut and egg custard filling, creating a dramatic dessert where the pumpkin both is the vessel and a delicious component.
Cultural Origin
Sangkaya Fak Thong is a classical Central Thai dessert of steamed coconut-egg custard set inside a hollowed kabocha pumpkin, with roots in palace cooking that drew on Portuguese-influenced egg desserts. It is a traditional holiday and family-meal sweet, often served sliced into wedges.

The pumpkin flesh nearest the shell picks up a faint savoury, vegetal note from steaming that plain coconut custard doesn't have, so each spoonful carries both the eggy sweetness of the custard and the mellow flesh of the squash.
How Sangkaya Fak Thong Is Made
- 1
Preparing the pumpkin
A whole kabocha pumpkin is cut open near the top and the seeds and fibres are scooped out to leave a clean shell.
- 2
Mixing the custard
Eggs, coconut milk, palm sugar, and pandan juice are whisked together until smooth.
- 3
Filling
The custard mixture is poured into the hollowed pumpkin, up to just below the rim.
- 4
Steaming
The filled pumpkin is steamed slowly until the custard sets firm and the pumpkin flesh softens without collapsing.
- 5
Cooling
It is left to cool before slicing, since a hot custard is too loose to hold a clean wedge.
- 6
Slicing
The whole pumpkin is cut into wedges through both custard and shell for serving.
When It’s Eaten
Served as a sliced dessert at room temperature or slightly warm, more often at home gatherings and special meals than as a grab-and-go street snack.

What people get wrong
Scooping out only the custard and leaving the pumpkin — the two are meant to be eaten together in the same spoonful, and the flesh close to the shell is where much of the flavour concentrates.

Tips
- The pumpkin flesh should be scooped with each spoonful of custard — the combination of savoury-sweet squash and fragrant coconut custard is the whole point.
