The fancy super-expensive raw cream that I bought at the farmers market last week has acquired a new smell and I'm wondering if it has gone bad. It's not technically past it's due date, and unfortunately I've only used half. It's smells a little pungent like cheeses can sometimes and not quite rotten. Can I use this to fatten up my mashed potatoes or should I archive it in the circular file? Any ideas?
Thanks for your help!
