Adding salt to the ice lowers the melting point of the ice, which allows the ice cream ingredients to freeze. (A 10% salt solution freezes at 20 degrees (F) .) Without the salt, the ice would melt at 32 degrees (F) but with the salt the melting temp drops to below the normal level. Adding the salt to the ice bag allows the ingredients in the inner bag attain a temp below 32 degrees (F) and therefore freeze. The agitation aerates the mixture and gives the contents the ice cream-ish consistency.
Now, time to go make some home-made ice cream!
