I found a container of sour cream that had migrated to the back of my fridge. It was still sealed but 2 months out of date. Upon opening, there was no sign of mold or unusual smell. We consumed it. We are still on this earth.
But here is a question--does turning a closed sour cream container on its head (lid) actually preserve the life of the sour cream? Or is it all an old wives' tale?
