Use of rock salt to make ice cream
Hundreds of millions of tons of rock salt are used every year, but most household consumers are familiar with rock salt cooking applications and can purchase hundreds of pounds of salt at a price, so foodstuffs One of several trips to the store. This salt is one of many products that are prudent to purchase in bulk, as salt will last for many years when stored properly.
Rock salt may be a common international product, but using it at home is often limited to freezing the roadway and making frozen dessert by hand. Children often like to use this common "ingredient" to make ice cream, but it is not a secret of cooking. In fact, the use of salt to make frozen treasure is based on simple chemistry. When salt is mixed with water, water freezes at lower temperatures. This means that a heat conducting surface (such as a metal can) can be cooled below the freezing temperature simply by adding salt to an ice or water bath.
Reducing the temperature of the heat conduction surface is not important to freeze the liquid in a uniform manner without freezing the food, but to uniformly freeze the texture of the creamy ice cream.
How much salt is needed
In fact it needs quite a bit of salt to freeze ice cream. In order to keep the temperature low and carry away heat from the ice cream itself, salt and ice must always be added to the ice bath. As the ice melts, the temperature will remain cold, but additional ice will quicken the freezing of the ice cream. Depending on the amount of ice cream, some rock salt containers may be needed. After all, one batch of homemade ice cream is never enough.
How to do extra salt
The good news is that you can reuse water. Indeed, salty water can extend the life of the detergent or even use it in a salt bath. After all, the various bath products contain salt to facilitate the decomposition of the chemicals in the bath. Since extra salt water tends to eliminate plant growth, you can clean the floor (as a pre-detergent rinse), clean the driveway, or prepare the property for construction.
Obviously, even after making frozen dairy desserts, this natural resource has many uses.
