Wash the sweet pumpkin thoroughly, remove the skin and seeds, and cut into large pieces.
Place the sweet pumpkin in a steamer and cook until fully tender.
Mash the cooked sweet pumpkin and let it cool.
In a bowl, combine the mashed sweet pumpkin, cream cheese, heavy cream, and sugar, and mix well.
Pass the mixture through a sieve to make it smooth.
Transfer into small glass jars or bowls and refrigerate for at least 2 hours until set.
Once chilled, garnish with nuts or herbs to finish.
