Saute the leeks, onions, celery, garlic and mushrooms until the onions are clear. Add the stock, nectar or water, tomato sauce and white wine. Bring to a heavy simmer and taste. Add the cayenne pepper and salt to taste.
Prepare the seafood and add to the pot, remembering to add first those things which take longest to cook. The various shellfish go in with the shells on.
Simmer until done. Serve in large bowls over spaghetti. By adding extra fish such as a lobster per person this will become a meal instead of a soup.
