I gently poach the shrimp in flavorful liquid and, after thoroughly chilling them, serve them alongside a bright and spicy Calabrian chili cocktail sauce for a classic recipe with a twist
In a large pot of water, combine the yellow onion, salt, peppercorns, and garlic. Bring to a boil over medium-high heat. While the water boils, fill a large mixing bowl with ice water.
Working in batches if needed, add the shrimp to the pot and cook until no longer opaque, about 2 to 3 minutes.
Use a slotted spoon to remove the shrimp from the hot water and add them directly to the ice bath to stop the cooking process.
Remove from the water and peel the shrimp, discarding the shells or reserving for another use. Add the shrimp to a baking sheet, then cover and chill until ready to serve.
In a small mixing bowl, whisk together the ketchup, lemon juice, horseradish, Calabrian chili paste, and Worcestershire sauce until combined. Season to taste with salt and pepper.
When ready to serve, cover a serving platter with crushed ice and top with the shrimp and lemon wedges. Serve with the cocktail sauce for dipping.
Notes
As soon as the shrimp are cooked I recommend transferring them to a bowl of ice water to stop the cooking process. This helps keep them from overcooking and gives them the best firm texture.
