Are you talking about this horrid thing that they serve in school cafeterias, dorms and camps called 'Train Wreck'?  Served on toast, salty, thin slices of beef that comes out of a jar, maybe a gelatinous gravy on top?   We had name for it in college that I probably should even mention here....

Our corn beef is wonderful!  But you have to soak it in water for a couple of hours before cooking to get out the excess salt.  

Himself is being treated to corn beef hash for supper.  He's ecstatic  :)
