Buttermilk how can I tell?

Question

I just started using buttermilk in some of my cooking, but how can I tell if it goes bad? I don't like the taste so I don't want to taste it, I use it for onion rings and chicken fried steak any of my coatings.

Answer 1

The sniff test usually works if you can remember what it's supposed to smell like fresh and it's not more than a few days after the pull date.

But how can you tell when blue cheese has gone bad?

Answer 2

It's bad when it separates into thin liquid with chunks.

Answer 3

The smell will be off.

Answer 4

HA! Drinking buttermilk takes some courage, I think, if we haven't grown up with it! Buttermilk smells kinda like sour yogurt from the lactic acid. Bad buttermilk smells like sour milk from the acetic acid and like bacteria from a toilet. How about freezing portions of it to thaw out when you make food with it? Like making ice cubes with it and keeping them in a bag in the freezer? Then you know it hasn't gone bad and can use as much as you want without worrying about it.
