In case of a coffee emergency (no milk) there is always, always, always a box of cupboard milk. This stuff stays fresh forever....or so I thought. Apparently they have expiration dates, and you should pay attention to that stamped date for a reason.
Exhibit A: A box of cupboard milk with an expiration date of 4/25/2007.
I was assuming it would still be good, it's pasturized using ultra high temperature!! Boy how wrong I was, it was so chunky it just sat in the sink until I squished it down the drain.
I guess there hasn't been a coffee emergency in a long, long time....
