Not deveining properly

Deveining is the most important part of the shrimp preparation process. While you can purchase cleaned shrimp, buying fresh shrimp is always a better option. As a result, you should be able to clean them yourself. Although removing the veins may appear to be a time-consuming and unnecessary task, it is critical. The vein is the shrimp's digestive tract, containing both undigested food and digested waste. Although eating the vein is not harmful, leaving the vein inside the shrimp will result in a gritty texture as well as a not-so-appealing thought while trying to enjoy them.

Simply use a small knife to shallowly slice the back of the shrimp, edge-to-edge, once the shell has been opened to access the vein. The vein could be transparent, dark, or completely absent. If you find a vein, slide the tip of your knife beneath it and pull it out.
