Clean the seafood: Before you start cooking, clean and prepare the seafood.
Cook and prepare the seafood accordingly. Cook the Mussels with garlic, carrot, celery and onion for 5 minutes in white wine. Cook the Lobster in salted water for 10 minutes. Cook the clams for 7 minutes. Cook the King Crab Legs for 8 minutes. Shuck the Oysters open. Soak the Whelks for 10 minutes in ice water and drain them from the water.
Arrange the seafood: Once the seafood is cooked/prepared, it's time to arrange it on a platter. You can get creative with the presentation, arranging the shellfish in a decorative pattern on a bed of ice or seaweed.
Serve with accompaniments: Finally, serve your fruit de mer with a variety of accompaniments, such as lemon wedges, tartar sauce, cocktail sauce and butter. You can also include a selection of bread, crackers to round out the platter.
