01 - Using a mandoline slicer or sharp chef's knife, cut potatoes into uniformly thin rounds approximately 1/16 to 1/8 inch thick for consistent frying.
02 - Rinse sliced potatoes thoroughly in cold water to eliminate surface starch. Drain completely and pat dry using clean kitchen towels or paper towels until no moisture remains.
03 - Pour oil into a deep, heavy-bottomed pan or deep fryer. Heat to 340°F, maintaining consistent temperature throughout frying process.
04 - Working in small batches to prevent overcrowding, carefully add potato slices to hot oil. Fry for 2-3 minutes, turning occasionally, until chips turn golden brown and achieve crisp texture.
05 - Remove chips using a slotted spoon and transfer to paper towel-lined tray. Season immediately with sea salt while hot, adding black pepper if desired.
06 - Allow chips to cool completely on wire rack for maximum crispness. Store in airtight container if not serving immediately.
