Cut the Potatoes. Use an apple corer or knife to cut potatoes into thick, rustic fry shapes. Irregular edges create more surface area for extra crunch.
Immediately place the cut potatoes into a bowl of cold water to prevent oxidation.
Start in Cold Water (Parboil for Texture)
Place the potatoes in a pot with the same cold water.
Bring to a gentle simmer — do not start in boiling water.
Cook until the potatoes are tender and just starting to break apart. They should be fragile but not disintegrating.
This step creates micro-cracks that lead to ultra crispy fries.
Dry and Chill
Carefully drain and allow the potatoes to steam dry completely.
Refrigerate for at least 1 hour, ideally overnight.
Chilling removes surface moisture and firms the fries for better frying structure.
First Fry (Low Temperature)
Heat duck fat to 250–300°F (about 270°F ideal).
Fry the potatoes until pale and slightly leathery — do not brown.
Remove and refrigerate again until fully chilled.
This stage sets the crust and can be held for up to 2 days before final frying.
Final Fry (High Temperature for Crispiness)
Increase duck fat temperature to 350–375°F.
Fry until deeply golden brown and shatteringly crisp.
Drain and season immediately while hot.
