I do scallops and shrimp on the FEC. The shellfish are marinated in butter, olive oil, pinch of chipotle powder, shallot and garlic. Sometimes I add a little wine, or lemon or lime juice. The shrimp absorb the marinade quickly. 5-10 minutes. The scallops take 1-2 hours.
You have to watch them. They cook quickly.
