Found this in the magazine Southern Living...I have seen pickled shrimp at Costco and they look so good so I found this and the picture looks alot like theirs. Hope it tastes as good! You could go ahead and save some time by buying peeled and devined raw shrimp. I am going to try and add some slivered or a few whole garlic to ours (we love garlic). It takes one day to let the shrimp marinate/chill.
