Chef's tips
Do not mash the potatoes into a purรฉe; uneven, broken chunks allow steam to escape and create the best crunchy edges. Let the potatoes sit undisturbed in the hot pan so a proper golden crust forms before stirring. If you have leftover boiled potatoes from the previous day, they will crisp even better.
Ingredient substitutions
- Speck โ smoked pancetta, though speck offers the authentic pine-smoke aroma
- unsalted butter โ traditional lard (strutto) or extra-virgin olive oil for a dairy-free version
Storage
Keep leftover potatoes in an airtight container in the refrigerator for up to three days.
Reheating
Reheat in a dry hot skillet over medium heat until sizzling and crisp again.
Common mistakes to avoid
- โขOver-mashing the potatoes into a smooth paste rather than leaving rustic crushed chunks.
- โขStirring constantly, which prevents the essential crispy brown crust from developing on the pan base.
- โขOver-salting early before tasting the natural saltiness released by the rendered speck.
