10 out of 10 MartiniDave the baggies worked a treat :-D Most successful technique out of all the ones I tried.... they loved the bacon.
diabolik.... Dressing crabs (and removing the dead mans fingers) is a bit like identifying poisonous fungi, ie... if you learn it from a book or pics on a forum you may be unsure what you are doing... if you make a mistake... you could be very ill or make a complete mess of the crab. Best if you can get someone to show you, you will learn alot quicker and can ask questions if you are unsure. Bug your local fishmonger if you have to (and have one) they always seem happy to talk shop... or anyone on a beach fishing for crabs ...
Saying that, its very easy to learn, and when shown once you wont forget. I don't know any websites off hand on this subject... if I come accross any, I'll post a link.
If all else fails, get yourself a good seafood cookbook and try and catch a sea food cooking program or two on the subject.... they are always pulling the legs off of crabs. The dead mens fingers themselves are just the feathery gills/lungs which can be just cut out with a knife.
