I accidentally left hummus on the counter and then went to bed...when I got up in the morning, I found it!!! Do I have to throw it out?
Nah, it should be fine coz it should have vinegar and oil in it, and probably preservatives too. Go for it, if it makes you sick but, then at least you'll know for next time :)
For me, I would still eat it. But if the clear plastic seal under the lid is all puffed up, it might be no good.
mmmmmm I don't think I'd trust it.
