I could have sworn there was a Cecil Adams column about how do you know sour cream had gone bad. Anyway, this is all I could find but it’s much the same thing.
My question is, I know when sour cream has gone bad. I want to know when blue cheese goes bad.
Think about it. Blue cheese is already smelly and moldy. And it has that bluish green mold on it. Penicillium I think it’s called. That is how I know my sour cream has turned. Blue cheese already has it. Think about it.
