[Rhodes22-list] Refrigerator - Icebox

[Bill Effros]

Robert,

Have you seen Roger's postings on this?

He used dry ice inside foam containers duct taped shut for week long 
adventures away from ice.  You have to know what's inside each 
container, and open them only once, when you're ready.  Roger could keep 
ice cream this way.

I have used frozen steaks along with "frozy water", hoping that the 
steaks would be un-frozy in time to be cooked and eaten.  You have to 
like rare steak to appreciate this technique.
