I feel like this is one of those products, like milk or eggs, that pretty much stay good, regardless of the date on the package, until, well, it goes bad, and you can tell. But with the sourness natural to sour cream, I'm wondering if I'm being too cavalier about the subject.
Right now I have a container of sour cream in the fridge that's been open about two weeks. It tastes okay, and doesn't expire until April 10th. But I'm wondering how that expiration date is affected once you've opened the product. Should I eat it?
