Reduce heat; simmer 10 minutes. Return to a boil. Add shrimp. Cook until bright pink and opaque, about 1 minute 45 seconds. Use a slotted spoon to transfer shrimp to a wire rack set over a rimmed baking sheet; cover with ice, and let cool, about 5 minutes. (To store, fill a bowl 3/4 full with ice. Put shrimp in resealable plastic bags. Place atop ice; cover with more ice. Refrigerate up to 1 day, replenishing ice as needed.). To serve, arrange shrimp along rim of an ice-filled bowl (or on a platter) accompanied by lemon slices and cocktail sauce or lemon aioli.
Boil a small amount of water in a saucepan. Fill a large saucepan with 1 to 2 inches (2.5 to 5 cm) of water and heat on the stove over high heat. Place a steamer rack inside of the saucepan as the water comes to a boil.1  If desired, you could add lemon juice and salt to the water instead of adding it to the shrimp. If working with jumbo or colossal shrimp, steam-cook for another 2 to 4 minutes. 2  Turn or stir the shrimp with a slotted spoon, spatula, or tongs after the first 5 minutes. 3  Cover the pan with a loose layer of aluminum foil to trap more of the steam inside.
