re: Do you purge your crawfish with salt?

People will offer scientific studies and anecdotal evidence. The easiest way to find out whether it has a perceptible effect or not is to try it out. If crawfish taste better for you after having purged them with salt than they do without purging, then it is pretty clear what you should do.

To answer your question, I haven't been able to tell a difference so I don't worry about purging.
