It's strange, but there are many people, all over the world who have strongly pre-fixed ideas on the matter of food.
In fact there are many things which are quite delicious but look quite revolting, or our imagination runs riot and we can't figure out how ANYBODY could touch, never mind cook and eat. Just the idea of those 'slimy' things jumping over our plates is too much! Actually they are delicious, tender as chicken but with a slightly fishy taste - A garlic butter (beurre maître d’hôtel) goes well with them and crusty bread dipped - what more could you want?

If you think all this is too much, just reflect on the fact that shrimp, lobdter etc are actually necessary to clean the seabed and are effectively the 'rubbish bins' of nature - but we all eat them....some more than others.
