How do you know if your mashed potatoes are bad?

There are a couple of ways you can tell if your mashed potatoes have gone bad.

* Smell. If the potatoes have a sour or off odor, they are likely bad.

* Texture. If the potatoes are slimy or watery, they are likely bad.

* Color. If the potatoes are dull gray or brown, they are likely bad.

* Taste. If the potatoes taste sour or bitter, they are likely bad.

If in doubt, it is always best to throw out mashed potatoes that you are not sure are fresh.
