Use this guide to clean, identify, and select shrimp.
1. Devein the shrimp by peeling the shell from it. Use a paring knife to make a shallow slit along the back from the head end to the tail end. Look for the black sand vein that runs along the center of the back. If the vein is there, use the tip of the knife to carefully remove and discard it, as shown. Rinse the shrimp under cold running water.
2. If desired, halve deveined shrimp by placing the shrimp, front side down, on a cutting board. Cut all the way through the shrimp lengthwise, making two pieces.
