Cook them immediately if they have been thawed for no more than three days! Once you cook them they will last at least for another four or five days in the fridge! If nothing else put them in a good shrimp marinade for about one half hour - then SMOKE them over mesquite or hickory wood for one hour. These will be eaten up before five days is over! Good Luck & Bon Aperitif!
Instructions. 1  If frozen, thaw the shrimp: Place the shrimp you want to cook in a colander in the sink and run cold water over them for about 5 minutes. 2  Toss the shrimp occasionally to make sure they are all exposed to the cold water.ne thing to note: Most shrimp has already been frozen once, and even the fresh shrimp sold at most seafood counters has usually been frozen and thawed. There's nothing wrong with buying thawed shrimp from the counter, but you should cook it within a day or two and it's best not to re-freeze it.
