Fair enough. Zero trolling: Have you considered just buying a half-pint (~250ml) of milk at the covenience store, instead of (presumably) wasting much more? Just an idea. :)
I have, and it still goes bad. I've done quarts and those still go bad. Pints might work but at that point it's just annoying because I have to head out for milk often. Soy milk works fine for me. I hate the idea of wasting/spoiling food and I've never had soy milk go bad.
