Devein Shrimp

Understanding what the 'vein' is, adds to the conversation. Vein is just a euphemism for the shrimp’s lower digestive tract, meaning it is filled with shrimp poop. It will not harm you, but it might taste a bit grainy.

Experts say you might not be able to taste the vein depending on the shrimp’s size. Small and medium shrimp tend to have smaller 'veins' and do not need deveining except for cosmetics. For larger ones it is usually a good idea to do it.
