Sour Milk Countermeasure

Just a throwaway little tip, but it may come in handy one day:

If you depend on milk (e.g. for coffee, cereal, or cooking), you will, at some point, be left stranded by a souring stash. So...I keep a few little aseptic boxes of low-fat organic milk in the back of my fridge. They last for months, and will get you through a pinch.
