I have been planning to post a video on how to clean prawn for so long. Finally I got a chance to create one. Cleaning Prawns is a tedious job which requires patience. Removing the shells is somewhat easier, but pulling off the vein is time consuming one.
Initially it took me around half an hour to clean 250 gms of prawns, but now it takes only 10-13 mins to clean them completely. You can make the work easier by following two steps. First is to remove the shells of all the prawns and then second step is to devein. I hope the step by step photos and the video will help the people who think cleaning prawns is a rocket science.
In restaurants, you could see that grilled prawns or barbequed ones would be served along with the tails attached. The tails make it easier to hold the prawns. So you can clean the prawns accordingly with the recipe in your mind.
There are two veins in prawn and people often get confused with which one to remove or some cleans both the veins. The vein present in the upper part of flesh has to be removed. You can post your queries in the comment section or just mail me if you still have any doubts.
