Sang Ka Ya Fak Tong turns a whole pumpkin into its own serving vessel: a coconut milk custard, lightly spiced with cinnamon and vanilla, gets poured directly into a hollowed-out pumpkin and steamed until firm, letting the pumpkin's own sweetness blend into the custard as it cooks. As the custard cools it naturally contracts, leaving a small gap at the top that's a perfect spot for a spoonful of cinnamon-nutmeg whipped cream, with the pumpkin's cut-off top serving as a lid to keep everything cold and fresh in the fridge. Sliced like a pie at the table, it's an eye-catching dessert built from a technique more commonly seen at Thai street food stalls than in home kitchens.
Ingredients
- 1 Small kabocha squash (pumpkin) (sized to hold the custard)
- 2 Chicken eggs
- 4 3/4 tablespoons Coconut milk
- 2 1/8 tablespoons Coconut sugar (softened with a little water if in block form)
- 1/8 teaspoon Salt
- 1/8 teaspoon Ground cinnamon
- 2/5 teaspoon Vanilla extract
- 6 1/2 tablespoons Heavy whipping cream
- 2/5 tablespoon White cane sugar
- 1/8 teaspoon Ground cinnamon
- 1/8 teaspoon Ground nutmeg
Directions
- Cut a hole in the top of the pumpkin with a sharp knife, keeping the cut-out top in one piece and large enough to fit your hand through.
- Use your hand and a spoon to remove all the seeds and stringy membrane until the inside is smooth and clean.
- If using block coconut sugar, soften it with a little water, heating briefly in the microwave until it mixes into a syrup. Skip this if using granulated sugar.
- Whisk the eggs lightly, then whisk in the sugar until well blended.
- Add the cinnamon, salt, and vanilla extract. Stir well, then add the coconut milk and whisk lightly until smooth and creamy.
- Pour the custard into the hollowed-out pumpkin.
- Place the pumpkin in a large steamer, laying the cut-off top piece alongside so it cooks too. Cover tightly and steam for about 45 minutes or more.
- The custard should expand and firm up as it cooks. Check with a meat thermometer for an internal temperature of at least 165°F (75°C), or test firmness with a toothpick. Don't stop cooking while it's still too soft — this can take up to an hour total.
- Remove from the steamer and cool to room temperature, then refrigerate until very cold. The custard will contract as it cools, usually leaving a small gap at the top.
- Whip the heavy cream until thick with firm peaks. Add the sugar, cinnamon, and nutmeg, and beat on high until well mixed and firm again.
- Spoon the whipped cream into the gap at the top and pack in well.
- Replace the pumpkin top as a lid, pressing it into the cream. If there's no gap for cream, skip this step or serve the cream on the side. Refrigerate until ready to serve.
- Slice like a pie to serve. Wrap any leftovers well in plastic and keep refrigerated — it keeps for several days if kept very cold.
Notes
Don't pull the custard from the steamer while it's still soft, even if the timing seems close — undercooked custard never fully sets once cooled, so check firmness with a toothpick before stopping.
Substitutions
Buttercup squash makes a good substitute for kabocha if that's not available — both have a similarly firm skin and sweet, moist flesh.
