1. Never put potato in firdge. 2. Cold makes starc turn to sugar. 3. High heat makes this sugar into acrylamide which is bad for the health and can cause cancer :). In my country we say potato is our second bread so it is very important to treat it right. It also makes the taste too sweet and the color looks like coal when you fry it. I want my siblings to eat healthy so I always keep them in cellar or dark box :).
