Method
Cook the seafood
- Bring the water and 2 teaspoons of the kosher salt to a boil in an 8-quart pot.
- Add the calamari and cook at a gentle boil for 1 to 2 minutes, until opaque and the thickest pieces register 145°F.
- Transfer the calamari with a slotted spoon to an 18x13-inch rimmed baking sheet.
- Return the water to a boil, add the shrimp, and cook for 2 to 3 minutes, until opaque and the thickest shrimp register 145°F.
- Transfer the shrimp to the baking sheet.
- Return the water to a boil, add the scallops, and cook for 3 to 4 minutes, until opaque and the thickest scallops register 145°F.
- Transfer the scallops to the baking sheet.
- Spread the seafood in a single layer and refrigerate for 15 to 20 minutes, until cooled.
Mix and marinate
- Whisk the olive oil, lemon juice, red wine vinegar, garlic, red pepper flakes, black pepper, and remaining 1 teaspoon kosher salt in a 5-quart bowl.
- Add the cooled seafood, parsley, celery, red onion, and olives, then toss to coat.
- Cover and refrigerate for 1 to 2 hours, tossing once halfway through.
- Serve chilled.
Notes
Avoid overcooking the seafood; remove each type as soon as it is opaque and reaches 145°F. Refrigerate leftovers for up to 2 days; freezing is not recommended. For a lower-sodium option, reduce the kosher salt.
