Halloween is here and no one can deny that pumpkin is totally IN right now!

So here we are introducing a Thai Jack O’Lantern treat called Sankaya or Thai Pumpkin Custard. Wonder what it is and how to make it? Please see the recipe below.

Sankaya or Thai pumpkin custard is a Thai-style inside out pumpkin pie in which a lightly sweetened coconut milk and egg custard is steamed inside of a hollowed out pumpkin. A perfect balance of textures, the steamed egg custard inside shows the influence of the Portuguese on Thai cuisine, who introduced the idea of adding eggs to desserts in the 1600’s.


  • 1 Kabocha squash (Japanese pumpkin)

  • 10 cups of water for steaming

  • 4-5 eggs

  • 3/4 cups coconut milk (rich Mae Ploy brand is perferred for desserts)

  • 1/3 cup of coconut palm sugar

  • pinch of salt

  • pinch of cinnamon

  • 1 tsp. vanilla extract (or frozen pandanus leaf or pandanus leaf flavoring)


  1. Cut out the pumpkin just like you would for Halloween. Cut out the top, remove all the seeds and the stringy insides.

  2. In a mixing bowl crack the eggs, add coconut milk, salt, cinnamon, vanilla and palm sugar. Stir well until the palm sugar is blended into the mixture.

  3. Pour the mixture into the pumpkin.

  4. Bring water to a boil in a steamer. Then place the pumpkin and the pumpkin lid inside the steamer basket. Don’t cover the pumpkin with the lid. Set the pumpkin lid in the steaming basket off to the side so it cooks too.

  5. Now place the basket onto the steamer and cover the basket with the lid. Steam for about 45 minutes.

  6. When you think it’s time, open the steamer and stick a fork into the custard to check if it is done. If the fork comes out all wet and runny you need to steam it a little longer.

  7. Remove the basket from the steamer and let the pumpkin cool down.

  8. When you are ready to serve, take a knife and cut a wedge out of the pumpkin just as if it were a pie. The custard should be firm enough to stand on its own and not be runny.

  9. Allow to cool to room temperature and serve to your guests. They can eat the entire pumpkin – the skin and flesh of the pumpkin and the creamy custard inside. Refrigerate any leftovers.
