I bought a quart of soy milk for the first time ever last week. It has been sitting unopened in the door of my refrigerator since. I pulled it out today to use it in a bowl of cereal and it was frozen solid.
My refrigerator is not particularly frigid; regular milk and juice products stored in the back do not freeze. It's even more shocking to me that it froze in the door of my fridge, since that is the warmest place.
Is this normal for soy milk? If not, what went wrong? How should I store soy milk?
*The expiration date is sometime in March 2011
