My mom keeps telling me it is unsafe to refrigerate leftover cooked potato in any form because she claims refrigeration accumulates toxins in them (or something like that). I, on the other hand, often refrigerate all forms of cooked potato, including but not limited to boiled, roasted, meshed etc. Often, I will boil a bunch of potatoes, refrigerate them and then just slightly sautee them with spices before eating.
Who is right? Can it be bad to eat leftover refrigerated potatoes?
