Now that I buy things like heavy cream, whole cottage cheese, and full-fat sour cream (which I like on EVERYTHING! in moderation, of course, of course), I would like to know how long these things will last before going bad, once they are opened. I know there are expiration dates, but the cream for example says it expires Dec 22 and I doubt that it can really last that long. Yes, I know to sniff for the rancid smell, but if anybody has rough lengths of time, I'd be appreciative.
Have a bang-up day!
