I don't see why this detail would ever have come up.  Suppose you're a 
caterer and I'm your loyal chef, and we're planning a menu which 
includes liver.  You tell me that it will be my job to kasher the liver, 
and I agree.  You think I know how to do that, and *I* think I know how 
to do that, but in fact I haven't got a clue. How would that play out? 
At what point would you realise that you have to teach me this halacha?
