Today's stupid question: yesterday I bought some organic low fat cottage cheese - i think the brand is Nancy's - instead of my usual Breakstone. Had some this morning and it tasted . . . odd. Sour. Not like sour milk, but like someone had mixed some sour cream into it. I'm guessing it was fine, i.e. not spoiled, since it didn't make me sick, but I didn't exactly love the taste. so I'm wondering if that's the way organic cottage cheese is supposed to be, and if yes what's different about it versus the usual super market brands.
