Rock salt is used because it causes the ice in the bucket to melt, but at the same time to be cold enough to freeze the ice cream inside of the canister. I am of course talking about the hand churned ice cream. If you didn't use salt, you would not be able to turn the canister to churn the ice cream mixture into a freezable substance.
When you make ice cream in a traditional hand-cranked ice cream maker, you use rock salt on the ice surrounding the inner container. This helps to form a brine that has a temperature below the freezing point of water alone, thereby speeding the ice cream freezing process.
Salt prevents things from freezing too much (i.e they freeze at a much lower temperature). This means that, generally, ice creams with salt in do not freeze quite as solidly as those without salt in.
Salt raises the freezing point of water, which is why municipalities use salt to cause the ice to melt from the roads. When making ice cream, using salt causes the ice to melt enough that the transfer of heat from the ice cream mixture is more rapid which makes the ice cream solidify faster.
Freezing point is a colligative property, which means that it is dependent on the amount (mass) of solute particles such as salt. Therefore salt causes a freezing point depression making it easier to freeze the ice cream.
The use of salt in making ice cream is because it will lower the freezing point of water, so the ice cream can get colder than it normally would without the salt. Water normally freezes at 0ºC but with more and more salt added, it can freeze at lower than -5ºC for example.
The salt does NOT go in the ice cream.
It's used to lower the melting point of ice that cools the ice cream.
Salt prevents ice from freezing, and requires even lower temperatures to remain in a dolis state. It will also change the taste.
Becuase it add extra flavour of course
and it taste better when the ice cream melts
salt is important in making ice cream because it lowers the freezing point of the ice which needs to be at least -10 degrees Celsius in order for the ice cream to freeze
You don't use rock salt in ice cream, unless you want salty ice cream. You use rock salt (though table salt or sea salt would work just about as well) in the freezer to get it colder than you could with a mixture of ice and water.
Most likely, yes.
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.
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.
Well, it does make it salty. In all seriousness though, if you add rock salt while making home made ice cream, it doesn't affect the flavor, but it makes it colder.
Salt inhibits freezing (it makes foods have a higher freezing point), which helps the ice cream to remain soft enough to eat straight from the fridge.
I believe that Morton Ice Cream Salt is just standard rock salt, used in making homemade ice cream.
Add salt to the ice to make it colder.
You don't ADD salt
Yes. The water is from the melting ice.
You don't use rock salt in ice cream, unless you want salty ice cream. You use rock salt (though table salt or sea salt would work just about as well) in the freezer to get it colder than you could with a mixture of ice and water.
Overrun is important in cream making because without it you will get a denser textured ice cream. Overrun is defined as the amount of air incorporated into the ice cream as you make it.
Salt lowers the freezing point of ice so when the temp. outside is lower then 32 degrees, the ice will still melt. When making ice cream, when the temp. is lowered, the energy given off is transfered to the ice cream making it freeze.
there are particals that they use.
Putting Salt (sodium Chloride) to the homemade Ice Cream stops it from turning into a big chunk of frozen milk. It gives it its consistancy.
small salt dissolves quicker

Adding salt to the ice causes the temperature of the brine solution to drop dramatically, while freezing the ice cream inside the container. As the ice melts, the "heat" of the ice mass is preserved by lowering the temperature. (It's called "latent heat") It takes approximately 80 calories of energy to melt a gram of ice. That latent heat principle is used to lower the temperature of melting ice, thereby allowing the ice cream to freeze. It's an example of simple physics and is described in most physics books and physics classes.
