Food Science: Achieving Maximum Crunch
-
Surface Amylose Extraction: Soaking sliced potato rounds in cold water strips excess free surface starches (amylose). Free surface starch causes slices to stick together and burn into a chewy coating rather than forming a crisp crust.
-
Surface Moisture Removal: Dehydrating the potato rounds thoroughly with towels before adding oil is critical. Trapped water under the oil layer turns into steam, resulting in soft, soggy potatoes.
-
Gelatinization in High Heat: Baking at 425°F (220°C) gelatinizes internal starches while evaporating remaining surface moisture. The oil coats the outer cell walls, triggering rapid surface browning and crisping.
