This is an easy, healthy, flavorful and spicy soup. It is an impressive first course for company if you use large or jumbo shrimp. Alternatively, you can use tiny shrimp and the cost will be much lower but the taste will be the same. It is a regular main dish for my family (using smaller shrimp) and for my annual 'soup party'. I found this recipe on southernfood.about.com and have improved upon it (in my opinion) since first posting by adding vinegar, red wine and Worcestershire sauce. These ingredients are noted as "optional'.
