This is my ice box in the restaurant but it is not only ice but fish in it.
Taka doesn't have a refrigerator? I have 3-4. But why do I use ice for keeping fish. There is a reason. Ice can keep fish longer than refrigerator. Ice's temperature is same all the time but refrigerator is not same.
And ice temperature ( it is between 32F and freezing temperature.) is a key. This condition can last fish longer.
I always do this. Understand?
