Peel the shrimp by flipping it over. Gently start pulling away from the shell, opening from where the legs are located. If keeping the tail on, make sure to carefully tear away the shell from that junction point.
If you want to remove the tail, firmly hold the body and pull the entire tail off.
Use a paring knife to make a long shallow cut down the length of the shrimps back, stopping at the tail.
Completely remove the digestive tract using your fingers, or a toothpick comes in handy for this task.
After cleaning, transfer the shrimp to a colander. Rinse well with cool running water for about 1 minute. Drain thoroughly and dry the shrimp with paper towels.
