Thaw that shrimp! Place unopened 1-lb. bag of shrimp in a large bowl and fill with cool water. Place a heavy plate on top to submerge until thawed, about 45 minutes. If you’re the kind of person who actually thinks about dinner more than a few hours before you’re going to make it, you can also let the shrimp thaw overnight in the fridge. Alternatively, if you’re in a hurry, take the shrimp out of the bag and let them soak in a big bowl of cold water—they’ll be ready in about 15 minutes. However you thaw them, make sure to pat them dry before proceeding. Season shrimp with 1 tsp. salt. Let sit until ready to use. While all that’s happening, bring a large pot of salted water to a boil.
