Wash the sweet pumpkin thoroughly, remove the skin and seeds, then cut into appropriate pieces.
Put the sweet pumpkin and water into a pot and bring to a boil.
Once the sweet pumpkin is fully cooked, mash it until smooth.
Add more water and sweet rice flour to the mashed pumpkin, and stir while boiling.
When the texture thickens, season with salt to taste.
Serve in a bowl to finish.
