What happens if you eat the black vein in a shrimp’s tail
Large shrimp: In larger shrimp, the vein is more visible and more likely to contain debris, so it’s recommended to remove it.
Small shrimp: In small shrimp, it’s often cooked with the whole thing because removing it can be tedious and its impact is minimal.
Delicate preparations: If you’re looking for a clean presentation or more subtle flavors (such as in ceviche or gourmet dishes), it’s best to remove it.
