- 4 large eggs
- 120 g palm sugar or white sugar
- 1 tsp pandan extract or 2 pandan leaves

Instructions
Step 1: Prepare the Pumpkin
Cut off the top of the pumpkin to create a lid. Scoop out seeds and fibers carefully, keeping the shell intact. Rinse and set aside.
Step 2: Make the Custard (Sang Khya)
In a bowl, whisk eggs gently. Add coconut milk, sugar, salt, and pandan. Mix slowly to avoid air bubbles.
Step 3: Strain the Custard

Step 4: Fill the Pumpkin
Pour the custard into the hollowed pumpkin, leaving some space at the top to prevent overflow.
Step 5: Steam
Place the pumpkin in a steamer over medium heat. Steam for 45–60 minutes until the custard is set and pumpkin flesh is tender.
