Melt butter in a large pan over medium heat. Add clam juice, white wine, cocktail sauce, celery seed, paprika, lemon juice, Worcestershire sauce, Tobasco, and celery seed to taste.
Stir in the seafood, then bring to a high boil. Add half-and-half, then bring the pan's contents back to a boil.
Put the butter in the bottom of a large bowl, add the pan roast, top with the paprika, and then serve.
