Wash the sweet pumpkin thoroughly and slice it thinly with the skin on.
Place the pumpkin slices in a steamer and cook for 10 minutes.
Mash the cooked pumpkin, then add eggs, salt, and milk. Mix well.
Pour the mixture into an earthenware pot.
When it starts to boil over medium-low heat, reduce to low heat, cover, and steam for 10 minutes.
When the steamed egg is fully set, it's done.
