Flash-freezing juice is more necessary than freezing many other drinks because adding ice cubes to the poured juice will dilute the beverage, causing it to lose its flavor. Flash-freeze your juice by initiating a chemical reaction. This method is often used by chefs to transform sauces and other liquids into frozen or semi-frozen items. The technique can also be applied at home on a hot day when you need a cold drink.
Place a container of juice in a large bowl and pour ice over it.
Add water to cover the juice. Add about a 1/4 cup of salt. The chemicals in the salt will cause the water and ice to become extremely cold.
Let the juice sit in the ice for about 30 seconds Remove the juice from the ice and serve.
