Salt on it's own will not make ice cream faster, however adding salt to a water + ice solution causes a chemical reaction which will lower the overall temperature to less that that of either the water or the ice which would then let a container in that solution reduce it's temperature a lot faster than usual (that is what helps make the ice cream faster); I will explain:

Water freezes at 0 degrees. By adding salt to water we now create a solution that is no longer water. This salt/water solution has a lower freezing temperature than water alone.

Now we add ice to this solution.

As the salt dissolved in the water starts the 'melt' the ice (the reason I have used quotes around 'melt' is because we are effectively seeing the ice melt but what we are actually doing is converting it into a liquid which will no longer be frozen at 0 degrees), a chemical reaction takes place which results in the energy used to 'melt' the ice being expelled as heat, therefore reducing the temperature of the whole salt/water+melting ice combination to as low as -22 degrees.

The same trick can be easily used to cool cans and bottles of drink very quickly - just get a bowl with some water and plenty of ice in it and add a couple of handfuls of salt. Stir it for a few moments and then put some cans of drink in it. About 5 minutes later, those drinks should be lovely and cold!

Why is salt added to ice cream when your making home aid ice in an ice cream freezer?

Salt acts as an antifreeze, reducing the melting/freezing point of the ice. This makes the salt & ice freezing mixture much colder than that of ordinary ice, causing the ice cream to freeze faster and with smaller crystals. An ice cream with smaller crystals feels smoother and creamier in the mouth.I use a compressor ice cream maker, which requires no salt & ice mixture as it has a built in electric powered freezer.


Can you use salt instead of rock salt to make homemade ice cream?

No.


Do rock salt or table salt freeze homemade ice cream faster?

No. But ice and water with table salt dissolved in it, can.The salt lowers the freezing temperature of the water, so that it can remainliquid even when it's below 32° Fahrenheit (0° Celsius). In that condition,it can be used to cool the can in which the ice cream ingredients are mixed, andcan freeze it faster than solid normal ice could.


Do you add salt to the ice or the ice cream ingredients?

You add salt to ice to lower the temperature of the ice/water mixture. Without the salt, the temperature would not fall below 32.F, which is not cold enough to make ice cream. The freezing point of salt water is below that temperature and thus allows the cream to partially freeze, a necessary part of making ice cream Salt causes water to freeze at a much lower temperature. Adding salt to the ice causes the temperature of the brine solution to drop dramatically, while freezing the ice cream inside the container.


Do you have to use rock salt to make homemade ice cream?

Yes u do .. Or you can buy a homemade ice-cream kit at you local grocery

You don't. To make ice cream you want to make it with ice cream salt.


Why is salt sprinkled to the ice in ice cream?

To lower freezing point, making the ice cream mix in the container colder than freezing temperature so it freezes faster. Its much easier to make ice cream with a compressor freezer than a salt & ice freezer.

What is the rule of salt in the ice cream cart?

Salt is used to keep the ice cream cold, and it is also what you use to make the ice cold enough in a machine, to make the cream form into a solid.

Do you need eggs to make homemade ice cream in a bag?

No. To make ice-cream in a bag, you do not need eggs. You need ice, sugar, milk, and salt to make ice cream in a bag.


Why is salt added to ice cream?

Why would you? I mean it's so disgusting! Only a weirdo would do that! It probably taste bitter and not so sweet. My advise DON'T DO IT!! :( A pinch of salt in anything sweet makes it taste better. You don't taste the salt. But in the case of ice cream, salt is sprinkled over the ice in an old fashion ice cream freezer to make the ice colder and make the ice cream freeze faster. I can't explain how salt makes the ice colder but it does.
