Why is the salt important when making ice cream?
Salt provides the solution. Similar to sugar, salt affects how water freezes and effectively lowers the freezing/melting point of water. Creating a saltwater slush and packing this around our ice cream base allows us to cool the base enough so that it starts to thicken and freeze before the ice melts completely.
How do you make ice cream with salt?
Into a large resealable plastic bag, combine ice and salt. Place small bag inside the bigger bag and shake vigorously, 7 to 10 minutes, until ice cream has hardened. Remove from bag and enjoy with your favorite ice cream toppings.

Therefore, we can’t use straight ice to chill the ice cream base, because the ice will melt before the base gets cold enough. Salt provides the solution. Similar to sugar, salt affects how water freezes and effectively lowers the freezing/melting point of water.
What is the freezing point of ice cream?
Water freezes at 0 degrees Celsius (32 degrees F) Other solutions have different freezing points. The fat and sugar in the mixture you prepare for making ice cream requires a colder temperature to reach its freezing point. Salt lowers the temperature at which water freezes.

Why do you add salt to ice water?
In both cases, the answer is based on the fact that adding salt to an ice water mixture in equilibrium, lowers the freezing point (or melting point) of the equilibrium.

Why do you use large crystals in ice cream?
Ideally, you would make your ice cream using ‘ice cream salt’, which is just salt sold as large crystals instead of the small crystals you see in table salt. The larger crystals take more time to dissolve in the water around the ice, which allows for even cooling of the ice cream.
