Method
- Cut a circular lid off the top of the pumpkin (about 8cm diameter). Scoop out and discard the seeds and stringy interior.
- Whisk the eggs in a wide bowl until pale and frothy. Whisk in coconut milk, palm sugar, cardamom, vanilla, salt and rosewater. Strain through a fine sieve into a clean bowl.
- Pour the custard mixture into the pumpkin cavity through the cut lid. Replace the lid.
- Set up a steamer with rapidly boiling water. Place the pumpkin on the steamer rack.
- Steam over medium-low heat (a hard boil makes the custard pock-marked) for 50–60 minutes — a skewer inserted into the custard should come out clean.
- Cool to room temperature; the custard sets further as it cools. Slice the pumpkin into wedges showing the pale custard centre and orange pumpkin around it. Serve at room temperature or chilled. The pumpkin flesh and custard are eaten together with a spoon.

Cultural Note
Sangkhya is the Khmer word for custard; lapov is pumpkin. The dish is one of the most beloved Cambodian desserts, sold from bakeries and afternoon markets in Phnom Penh and Siem Reap. The technique — steaming custard inside a vegetable cavity — is used in other Southeast Asian dishes (Thai kanom mor kaeng buak, Vietnamese banh bi quy) but the Cambodian version is distinct in the gentle palm-sugar sweetness and the addition of cardamom or rosewater. The dish is associated with Cambodian celebrations and is sold as breakfast in some Phnom Penh bakeries.
