Steps
1. Bring a pot of salted water to a boil and cook the Argentine shrimp for 2-3 minutes until they turn pink and opaque. Drain and immediately transfer to an ice bath to stop cooking.
2. In a small bowl, mix ketchup, horseradish, Worcestershire sauce, lemon juice, hot sauce, salt, and pepper to make the cocktail sauce.
3. Drain the shrimp from the ice bath and pat dry.
4. Arrange the chilled shrimp on a serving dish over some ice cubes.
5. Spoon the cocktail sauce into a small bowl or drizzle over the shrimp.
6. Garnish with lemon wedges and fresh parsley or cilantro.
7. Serve immediately, allowing guests to dip the shrimp into the sauce and enjoy the refreshing zesty flavors.
