Many people use the freezing method to save future time on preparing food.
The freezer actually acts as a pausing time machine, keeping your food as fresh as the first day for weeks or even months.
However, not any food can handle being frozen. Some foods could even turn quite harmful for your health if they were put in the freezer.
Raw potatoes can become unpleasantly black in the freezer, mainly due to their high water content.
The best storage for this vegetable is to keep it in a cool dark place instead.
However, cooked potatoes and puree can be safely put in the freezer, without any damage to their quality.
