How long is tomato sauce good once opened?
I have a half jar of nice sauce in the fridge that I opened two weeks ago today. Is it still OK? What about "fresh" sauces once they are opened? any difference?
thanks, sorry such an elementary question
There is no such thing as a firm OK or not OK. It depends on the temperature is was stored at, how long it was kept at room temp after opening, and among other things how much bacteria "got in" when you opened it.
My genereal rule, if there's nothing fuzzy growing in it, heat it thoroughly and you should be OK.
It's been my experience that the mold starts on the bottom of the lid. If I don't see any and it taste ok, I use it. Sometimes it goes in a week, sometimes it's ok after 3 or 4.
They're right, mold will be the sign. It depends so much on the ingedients as to how soon it will happen.
Tomato sauce can also ferment, and get a tangy taste.
Look for small bubbles on top, around the edge of the container.
FYI, even if it has gone bad, it will not be dangerous to eat, it will just taste bad.
