Sangkaya Faktong (Thai Kabocha Pumpkin Custard) Recipe
Introduction
Sangkaya Faktong is a delightful Thai dessert that features a creamy pumpkin custard steamed inside a kabocha pumpkin shell. This dish combines the natural sweetness of kabocha with rich coconut milk and eggs, resulting in a smooth, fragrant dessert perfect for any occasion.

Ingredients
- 500g Kabocha Pumpkin (about 1 medium pumpkin)
- 400ml Coconut Milk
- 3 Large Eggs
- 100g Palm Sugar (adjust to taste)
- 1 pinch Salt
- 2-3 Pandan Leaves (optional)
Instructions
- Step 1: Cut the kabocha pumpkin in half and scoop out the seeds. Steam or boil the pumpkin until very soft, then mash or puree it until smooth to create a seamless texture for the custard.
- Step 2: In a bowl, whisk together the eggs, palm sugar, and a pinch of salt until well blended. Gently warm the coconut milk, then slowly add it to the egg mixture, stirring continuously to prevent the eggs from cooking.
- Step 3: Fold the pumpkin puree evenly into the custard mixture. Add pandan leaves now if using, to infuse a subtle floral aroma during steaming.
- Step 4: Pour the mixture into the pumpkin shells or into custard molds. Cover with foil or a lid to keep water from dripping inside, and steam over medium heat for 30-40 minutes, or until the custard is set but tender in the center.
- Step 5: Allow the custard to cool to room temperature before refrigerating. Serve chilled to enjoy the best creamy texture and refreshing flavor.
Tips & Variations
- Use pandan leaves for authentic aroma, or substitute with vanilla bean for a different but complementary fragrance.
- Adjust palm sugar quantity based on your preferred sweetness level.
- If kabocha pumpkins are unavailable, small sugar pumpkins can be used as a substitute.
Storage
Store the custard in the refrigerator, covered, for up to 3 days. Reheat gently with steam if preferred warm, but it is traditionally served chilled for best texture and flavor.

FAQs
Can I use regular sugar instead of palm sugar?
Yes, you can substitute palm sugar with regular granulated sugar or brown sugar, but the flavor will be less caramel-like and slightly different from the traditional taste.
How do I know when the custard is fully cooked?
The custard is done when it is set on the edges but still slightly tender and jiggly in the center. Avoid overcooking to maintain a smooth and creamy texture.

Ingredients
Main Ingredients
- 500g Kabocha Pumpkin (about 1 medium pumpkin)
- 400ml Coconut Milk
- 3 Large Eggs
- 100g Palm Sugar (adjust to taste)
- 1 pinch Salt
- 2–3 Pandan Leaves (optional)
Instructions
- Prepare the Pumpkin: Cut the kabocha pumpkin in half and scoop out the seeds. Steam or boil the pumpkin until it is very soft, then mash or puree it until smooth to ensure it blends seamlessly into the custard base.
- Make the Custard Mixture: In a mixing bowl, whisk together the eggs, palm sugar, and a pinch of salt until well combined. Gently warm the coconut milk, then slowly add it to the egg mixture while stirring continuously to avoid cooking the eggs, forming a silky custard base.
- Combine Pumpkin and Custard: Fold the smooth pumpkin puree evenly into the custard mixture. If desired, add pandan leaves at this point to infuse a subtle floral aroma and flavor during steaming.
- Steam the Custard: Pour the mixture back into the pumpkin shells or custard molds. Cover with foil or a lid to prevent water from dripping into the custard, then steam over medium heat for about 30-40 minutes until the custard is set but remains tender in the center.
- Cool and Serve: Allow the custard to cool to room temperature before refrigerating. Serve chilled to enjoy the best creamy texture and refreshing taste.
Notes
- Adjust the palm sugar amount based on your preferred sweetness level.
- If pandan leaves are unavailable, you can omit them—the custard will still have wonderful flavor.
- Ensure the steaming water does not boil vigorously to avoid water dripping into and affecting the custard texture.
- Use a fork to test if the custard is set; it should be tender but not liquid in the center.
- This dessert is best served chilled and can be stored in the refrigerator for up to 2 days.
