1-Step 1: Set up the poaching potFill a large saucepan about 3/4 full with water. Add 1/2 teaspoon salt, and if you want extra flavor, squeeze in the juice from 1/2 lemon and drop in the peel and flesh. Add 8 to 10 peppercorns and a handful of fresh parsley if you are using them. This small step gives the shrimp cocktail a more layered taste without making the recipe complicated.Bring the water to a rapid boil over high heat. Once it is boiling, remove the pan from the heat and let it stop boiling. This is an important trick for tender shrimp because the water stays hot enough to cook them gently without turning them tough.

2-Step 2: Poach the shrimpAdd the 24 shrimp to the hot water and stir once so they cook evenly. Cover the pan and let the shrimp sit for 4 to 5 minutes, or until they are opaque and pink. Large shrimp usually cook quickly, so keep an eye on them. Frozen shrimp that have been thawed may need a little more time, but they should still be cooked only until just done.For the best classic shrimp cocktail, stop cooking as soon as the shrimp turn pink and firm. Overcooked shrimp get rubbery fast.If you are cooking for guests with simpler tastes, you can leave out the optional lemon, peppercorns, and parsley. If you like a more fragrant result, those aromatics are a nice touch and make the kitchen smell great.

3-Step 3: Cool the shrimp fastPrepare an ice bath in a large bowl with 2 cups ice cubes and cold water. Drain the shrimp right away and move them into the ice bath. Let them cool for a few minutes so the cooking stops completely. This keeps the texture tender and fresh.Once the shrimp are chilled, drain them well. If you are making the shrimp cocktail ahead of time, you can refrigerate the cooked shrimp for up to 12 hours before serving. That makes this a very practical appetizer for holidays, dinner parties, and busy weeknights.

4-Step 4: Peel and keep the tails onPeel the shrimp, but leave the tails on. The tails make the presentation look elegant, and they also give guests a handy place to hold while dipping. If your shrimp were already peeled, just keep the tails in place if possible. Deveined shrimp are best because they save time and look cleaner on the plate.

5-Step 5: Mix the cocktail sauceIn a medium bowl, mix 1 cup ketchup, 2 tablespoons horseradish, and a pinch of salt. If you want more flavor, add 1 teaspoon lemon juice, 1/2 teaspoon Worcestershire sauce, and 1/2 teaspoon hot sauce. Stir everything together until smooth.Taste the sauce and adjust the horseradish if needed. Some people like a mild sauce, while others want a strong bite. That is the beauty of making shrimp cocktail at home. You can match the sauce to your own taste.

6-Step 6: Plate and serveDivide the sauce into 4 small bowls, wine glasses, or martini glasses. Hang the shrimp from the rims for a classic restaurant-style look. You can also arrange them around a bowl of sauce on a bed of ice if you want a more casual party tray.Serve the shrimp cocktail right away while the shrimp are cold. The mix of chilled shrimp and spicy sauce is what makes this appetizer so popular. It feels fresh, simple, and a little bit special at the same time.
