Hi there, my wife made mashed potatoes the other day and we then put them in the refrigerator.
Opening them up today there are pale orange spots over the potatoes, almost looks like food coloring.
It does not look like a mold growing on top but looks to be in the actual food. Any ideas?
I think that your wife was probably breeding mold without even knowing it if the mashed potatoes were refrigerated after being cooked, for 2-3 days or more.
Remember that the mold can develop in certain conditions in a short period of time.
Clean your refrigerator with baking soda and vinegar just in case that some mold spores were spread to prevent them from damaging more food.
When possible try to cook the potatoes on the same day that they will be consumed.
On the other hand, if you think about it everybody at some point is busy and needs to cook in ahead of time or just want to save some leftovers for the next day.
You can save mashed potatoes on the freezer but the structure of the potato will change and as a consequence will be less nutritious.
You could also save them in the refrigerator by using containers that make the food last longer.
These containers seem to work decently but you need make sure to wash and dry them completely before storing potatoes or any other food.
Tips:
Don’t let the potatoes stand outside too much time before storing them.
Is important to check the containers daily and to use some towel to dry the humidity that forms under the lid and the container itself.
And remember to eat the cooked food that was saved in the refrigerator within a week or less.
