In a large saucepan, combine the peppercorns, coriander seeds, celery, tarragon, thyme, parsley, Essence, salt, cayenne pepper, lemon juice, white wine, water and bay leaves and bring to a boil over high heat and cook for 5 minutes. Add the shrimp to the boiling water, stir, cover and remove from the heat. Let stand for 8 to 10 minutes, or until shrimp are just cooked through.
Strain in a colander and transfer the shrimp to a large bowl. Discard the cooking liquid and seasonings. Refrigerate the shrimp until well chilled, about 1 hour. While the shrimp are chilling, make the Cocktail Sauce.
When ready to serve, divide the shrimp among 4 small bowls, and hang them on the rim of each bowl. Divide the cocktail sauce into 4 equal portions and place in the bottom of each bowl. Garnish each bowl with a lemon wedge. Alternatively, you can arrange a layer of crushed ice in the bottom of 4 bowls, put a small ramekin of the cocktail sauce in the ice and arrange the shrimp on the ice around the sauce.
