Boil the peeled potato in 20ml of water until it is completely soft and cooked through.

Mash the cooked potato in a bowl and while still hot, add the room temperature butter, salt, and sugar. Mix well until smooth.

Repeat this process until all the dough is used.

Heat the mixture over medium heat, stirring continuously until the sauce thickens.

Serve warm for a delightful snack or appetizer.
