I saw this video on how this guy prepares his crayfish for the cooking. Is this how you folks prepare them before a crawfish boil? He pulls their guts out their rear (alimentary canal he calls it...)?
See this video and fastforward to about the 1:30 mark:
CC, We saturate the crawfish live in salty water for about 15 mins. in order for them to evacuate mud and (whatever) is in their system. Then we dump the crawfish live into a pot of seasoned boiling water...let the water come back up to a vigorous boil for ~2-3 minutes. Turn off the heat source and let them soak for approx. 45 mins to an hour. We don't pull the heads off until we are eating them.
