Prepare the ingredients: potatoes, salt, butter, and sugar.

Peel the potatoes.

Cut the potatoes into bite-sized pieces. Skip this step if using baby potatoes.

Perform the 'rolling cut' technique by trimming the edges of the potatoes for a rounded shape.

Boil the potatoes in salted water until tender.

Cool the boiled potatoes in the fridge or freezer briefly to prevent them from breaking during roasting.

Melt butter in a pan over low heat and mix in salt and sugar.
