How Long to Cook Dry Sea Scallops (U/10 or U/15) in the cast iron
Specification: Large "dry" (untreated) sea scallops, side muscle removed, patted bone-dry
3-Step Execution Protocol
Heat cast iron skillet over Ripping hot — 500°F (260°C) surface, oil just short of smoke until lightly smoking. Prepare dry sea scallops (u/10 or u/15) (Large "dry" (untreated) sea scallops, side muscle removed, patted bone-dry).
Cook for 3–4 mins total (90 seconds per side). Flip at the 2-minute mark for even browning.
A deep mahogany crust releases from the iron on its own — if a scallop sticks when nudged, it is not ready to flip. Confirm internal temperature reaches 145°F / opaque and pearly at the centre. Rest for 0 minutes before serving.
USDA FSIS 145°F seafood minimum internal temperature; "dry" scallop convention per FDA seafood labelling guidance (wet-packed scallops carry added sodium tripolyphosphate that prevents crust formation).
