I had a weird yogurt experience for me (a first in all of my years of eating yogurt): I opened up a cup of Trader Joe's European Style Chocolate Yogurt and it was completely liquefied. Not just a bit of liquid on top, but an entire cup of chocolatey liquid (the consistency of water, not drinkable yogurt). Anyone ever had this happen? Did I just get a cup of whey? And how does that make it through the manufacturing and packaging process?
