How does one know when buttermilk has spoiled?

[Zinfandel]

Hmmm, If it's rock solid, should I assume?

1. Well..

you CAN'T say it's bad ....just because it has chunks in it.....

[MichaelHarris]

2. I throw up when I see it on the shelf in the store so

I'm no help

[Zinfandel]

3. I was told when it hardens, to just use it as sour cream...

and scoop it out...yummm!

Yes, the smell is overwhelming, have I been given bad advice?

(Keep in mind) I just love it!

4. Get somebody else to taste it.

I hate it, but not because of the way it tastes - it's just how nasty the glass looks when you're through!

[Zinfandel]

5. Thanks, I won't use a glass.

6. When it tastes shitty

[Zinfandel]

7. But come on, it never tastes "shitty"

[Don_G]

8. I Have No Idea

I've never let it linger long enough in the fridge to find out.

9. When it grows mold

If, when you pour it, clumpy, fuzzy, hunks of mold come out, then it's gone bad.

10. When it's potable?

I figure it's gotta go the other way eventually. Yuk.
