In a stock pot combine the seafood boil with 6 quarts of water and bring to a boil. Add the sausage and boil for 5 minutes. Add the corn and cook for 5 minutes longer. Add the shrimp to the pot and cook until pink and firm and the corn is crisp and tender, about 3 minutes. Drain immediately and serve. 8 servings.
NOTE: If you can't fine hot smoked sausage, use a smoked kielbasa and add 1/2 teaspoon crushed red pepper per serving to the pot.
