Freeze using water that does not contain air as much as possible.
Freeze over time without quick freezing.

With these two, you can easily make ice that is difficult to melt.

The reason is that tap water contains a large amount of air, so the more ice touches the air, the faster it melts. As a breakthrough, tap water is boiled and cooled. By doing so, the air in the water will escape, and ice that is difficult to melt will be formed.

In addition, it costs a little, but if you boil commercially available natural water and then freeze it, there are few impurities, so you can make clearer ice.

Another. Slow freezing creates larger ice crystals that make the ice harder to thaw. It is based on the theory that it takes longer to unravel when large crystals are connected than when small crystals are connected.

Put an ice tray in the bag and it will freeze slowly. If possible, the trick is to reduce the temperature inside the freezer (raise the temperature).

By the way, do you know why the ice at Kakigori is hard to melt? The reason is that it takes about 50 hours to freeze at -9 degrees Celsius (about 20 degrees Celsius in the freezer at home).
