1-First Step: Set up the poaching water Fill a large saucepan about 3/4 full with water. Add 1/2 teaspoon salt so the water has a light seasoning. If you want more flavor, add the juice from 1/2 lemon, the lemon peel, 8-10 peppercorns, and a handful of fresh parsley. These extras are optional, but they give the shrimp a pleasant background taste. Place the pan over high heat and bring the water to a rapid boil. Once it reaches a strong boil, remove the pan from the heat right away. Let the boiling stop before adding the shrimp. This is the key to keeping the shrimp tender instead of rubbery.

2-Second Step: Add the shrimp and let them cook gently Add the 24 large shrimp to the hot water and stir them once so they cook evenly. Cover the pan and let the shrimp sit for 4 to 5 minutes. During this time, the residual heat cooks them through without harsh boiling. Watch for the color change. The shrimp should turn opaque and pink. That is your sign they are done. If you are using frozen shrimp that were thawed first, they may need a little extra time, but still keep the cook gentle and short.

3-Third Step: Chill the shrimp fast While the shrimp cook, prepare an ice bath in a large bowl using ice cubes and cold water. As soon as the shrimp are opaque and pink, drain them immediately and move them into the ice bath. This stops the cooking and helps lock in the tender texture. Let the shrimp sit in the cold water until they are fully chilled. This step matters because Classic Shrimp Cocktail should be served cold, not just cool.

4-Fourth Step: Peel and prep for serving Drain the chilled shrimp and peel them if needed, leaving the tails on for a nicer presentation. Easy-peel shrimp make this part fast, which is helpful on busy weeknights or before guests arrive. Leaving the tails attached helps the shrimp look neat when you hang them from the rim of small glasses or bowls. It also makes them easier to pick up and dip.

5-Fifth Step: Make the cocktail sauce In a medium bowl, combine 1 cup ketchup, 2 tablespoons horseradish, and a pinch of salt. Add the optional 1 teaspoon lemon juice, 1/2 teaspoon Worcestershire sauce, and 1/2 teaspoon hot sauce if you want extra tang and depth. Stir well, then taste the sauce. If you like a stronger kick, add a little more horseradish. If you prefer a milder sauce, keep it simple with just ketchup and a smaller amount of horseradish. This sauce is very easy to adjust for different tastes.

6-Final Step: Plate and serve Divide the sauce into 4 small bowls or glasses. Hang the shrimp from the rims so each serving looks neat and inviting. If you want to keep everything cold for longer, set the bowls on a tray of ice. Serve right away for the best texture and flavor.
