Now, you don’t HAVE to take the vein (that dark line up the back of the shrimp) out, but lots of folks prefer their shrimpies that way. Pull off the shell by wiggling it apart at the bottom of the shrimp. Once the shell is off, cut a shallow line along the top of the shrimp where the vein is, pull it out with the tip of the knife and…you’re done! Put the shrimp shells in a zippered plastic bag when you toss them out, because if they sit in your trash can for more than a few hours…well, I’ll let you use your imagination.
