Will yogurt go bad if left out?

While yogurt will generally keep well, left out overnight, it can quickly start to develop mold and mildew. The good news is, this is an easy thing to fix.

If you think this has happened, don’t just toss the yogurt. Try heating it up, mixing in a little more milk, or flavoring it with fresh fruit.
