Steam Oven Recipe: Thai Pumpkin Custard
Sang Kaya Fug Tong (Thai Pumpkin Custard)
Sang Kaya Fug Tong is a beloved Thai dessert that beautifully marries the rich, creamy texture of coconut custard with the earthy sweetness of pumpkin.1 Traditionally, this delightful custard is steamed directly inside a whole pumpkin, making for a stunning presentation and infusing the custard with subtle pumpkin flavour.2 It's a treat that's both comforting and exotic, perfect for sharing.
Ingredients:
- For the Custard:
- 3 large eggs
- 1 cup (240ml) coconut milk (full-fat for best results)3
- 3/4 cup (150g) palm sugar (or light brown sugar), finely chopped
- 1/2 teaspoon salt4
- 1 teaspoon pandan extract (optional, for fragrance and green hue)
- For the Pumpkin:
- 1 medium-sized pumpkin (about 1.5 - 2 kg), preferably a kabocha or Hokkaido pumpkin, which holds its shape well when steamed.
Equipment:
- Steam oven
- Large bowl
- Whisk
- Fine-mesh sieve5
- Spoon or scoop
- Paring knife
Instructions and Method:
1. Prepare the Pumpkin:
- Wash and Dry: Thoroughly wash the outside of the pumpkin and pat it dry.
- Cut the Lid: Carefully cut a circular lid around the stem of the pumpkin, about 3-4 inches in diameter. A sharp paring knife works best.
- Scoop out Seeds: Using a spoon or scoop, remove all the seeds and stringy bits from inside the pumpkin.6 Scrape the walls clean, but be gentle not to puncture the pumpkin flesh.
- Prepare for Steaming: Place the cleaned pumpkin (without the lid) in a suitable steaming tray or dish that fits your steam oven.
2. Prepare the Custard:
- Combine Ingredients: In a large bowl, combine the eggs, coconut milk, palm sugar, and salt.7
- Whisk Well: Whisk vigorously until the palm sugar is completely dissolved and all ingredients are well combined. The mixture should be smooth.
- Strain (Important!): To ensure a silky-smooth custard, strain the mixture through a fine-mesh sieve into another clean bowl. This removes any eggy bits or undissolved sugar, preventing a lumpy custard. If using pandan extract, stir it in after straining.
3. Fill and Steam:
- Fill the Pumpkin: Carefully pour the strained custard mixture into the hollowed-out pumpkin.8 Fill it almost to the brim, leaving about 1/2 inch space from the top as the custard will expand slightly during steaming.
- Place the Lid: Gently place the pumpkin lid back on top of the pumpkin.
- Steam Oven Setting: Place the pumpkin in your steam oven. Set the steam oven to 100°C (212°F) on the steam function.
- Steam Time: Steam for approximately 45-60 minutes, or until the custard is set. To check for doneness, insert a thin skewer or toothpick into the centre of the custard; it should come out clean. The steaming time will vary depending on the size of your pumpkin and the power of your steam oven.
4. Cool and Serve:
- Cooling: Once cooked, carefully remove the pumpkin from the steam oven. Let it cool completely at room temperature for at least 1-2 hours before slicing. Cooling allows the custard to firm up and makes for cleaner slices.
- Slice and Serve: Once cooled, you can slice the pumpkin into wedges, with each wedge containing a portion of the delicious custard.9 Serve at room temperature or chilled.
Tips for Success:
- Pumpkin Choice: Kabocha or Hokkaido pumpkins are ideal as they have a denser flesh that holds up well during steaming and a naturally sweet flavour. Avoid pumpkins with thin walls.
- Preventing Cracks: If your pumpkin is very thin-skinned, you might consider wrapping the outside of the pumpkin with aluminium foil during steaming to help prevent it from cracking.
- Perfect Custard: Straining the custard mixture is crucial for a smooth, lump-free texture. Don't skip this step!
- Palm Sugar: Palm sugar adds a unique caramel-like flavour that is characteristic of Thai desserts.10 If you can't find it, light brown sugar is a good substitute, but the flavour will be slightly different.
- Pandan Extract: While optional, pandan extract adds a beautiful aroma and a subtle green tint to the custard, enhancing the authentic Thai experience.
- Don't Overcook: Overcooking can lead to a rubbery custard. Keep an eye on the cooking time and test for doneness regularly.
- Chilling for Better Slicing: While delicious warm, the custard becomes firmer and easier to slice neatly when chilled for a few hours in the refrigerator.
Enjoy your homemade Sang Kaya Fug Tong! It's a unique and delightful dessert that's sure to impress.
