- Heat some water to a boil in a medium-size pot, then reduce to a simmer. Add shrimp and cook for about 1 minute, or until just cooked through, and place immediately in a bowl of ice water. Add calamari to the pot, cook for about 20 seconds, and add to the bowl of ice water. Drain shrimp and calamari well.
