Fresh shrimp smell like sea water. There should be no off-odors, mustiness or chemical smells. Occasionally shrimp will smell and taste like iodine. This is not related to spoilage and is not harmful, but makes them unacceptable for eating. Certain organisms on which shrimp sometimes feed can cause this iodine effect. If you buy shrimp that smell this way, return them to your market for a refund or replacement.
In large cooker, bring water to rolling boil. Add seasoning. Add potatoes and onions. Continue to boil until potatoes are almost done, about 10 minutes. Add corn and cook until done, about 3 minutes. Add shrimp and cook until done, about 3 to 5 minutes. Drain and serve. Serves 12 to 15.
Note: Many people like to shake additional Old Bay over the food after draining it. Also, you can add smoked sausage to the pot. Cut into pieces about 1 ½-inches long and add after the potatoes. Other seafood seasonings can be used for flavor. Follow package instructions for amounts and cooking methods.
