How to devein a prawn

When buying tiger or king prawns (smaller sized prawns such as the North Atlantic are often already prepared), it is important to check if they have been deveined before cooking. The 'vein' is the black line that runs down the back of a shelled prawn. This black line is, in fact, the intestinal tract of the prawn. It isn't harmful but the prawn will be more pleasant to eat if removed.

1
Using a small, sharp knife carefully cut a small line into the prawn by running down the length of the prawn’s back
2
With the tip of the knife, remove the black intestine and discard
