Rinse the potato slices under running water to remove excess starch.

Soak the potato slices in cold water for 5 minutes, then drain and pat dry.

Heat a pan and stir-fry the smoked duck until its fat is rendered.

Add the dried potato slices to the pan and stir-fry with the duck fat.

Season the potatoes with a pinch of salt and stir-fry until fully cooked.

Sprinkle black pepper to taste and stir well.
