Adding salt lowers the freezing temperature of the water and for wintery roads, it means that the water won't freeze as easily. For our ice cream, it allows the temperature of the mixture around the ice cream to get colder. Since the ice cream isn't just water, it needs to be a little below 32°F to freeze

If you were to simply use ice without salt, the ice would melt and grow warm well before your ice cream was ever complete. The weird homemade saltwater mix that develops around your ice cream as you turn that crank is actually colder than regular ice cubes, which is why adding salt to ice is imperative for making kickass ice cream.
