My cheese congealed and I don’t know why? I mixed up a salad in a glass container I added dressing and goat cheese crumbles and shook it up. The next day when I went to eat it all the cheese ended up in a big congealed lump in the bottom of the container.  Did I do something wrong?
I can't comment to ask a question yet, so I'll try to phrase it as an answer. IF you used a vinaigrette, it could be possible that the vinegar broke down the cheese and/or the oil congealed in the fridge, like someone else mentioned.
