If you need to defrost the shrimp, place for 10 minutes in a large bowl filled with cool water. After 10 minutes, replace the water with fresh cool water and allow to soak for 10 more minutes. Transfer the shrimp to a colander and rinse with cool water.
While shrimp are thawing, fill a large stockpot with water. Add 1 tablespoon kosher salt. Bring to a boil over high heat.
Add the thawed shrimp to the boiling water. Gently stir. Cover, remove from heat, and allow to cook for 10 minutes.
Using a slotted spatula, transfer the cooked shrimp to a platter. Cover and refrigerate 2 hours.
Serve the boiled peeled shrimp with cocktail sauce or drawn butter.
