I was eating lunch on Friday at work when I noticed that there was a bottle of salad dressing sitting in the shelf across from me. I looked at it mildly disgusted/confused on why someone would not put it away in the refrigerator. The concern quickly diminished as I got wrapped up in my turkey and provolone sandwich. A few minutes later a woman I work with came in and poured the dressing on her salad. I couldn't resist asking her why she would keep salad dressing at room temperature which is when she informed me that she had made this dressing at her house with fresh herbs and olive oil. Things still weren't clicking in my head. She could obviously still see the confusion on my face and thats when she informed me that olive oil coagulates when it gets cold. (Coagulating means that it hardens, FYI.) I'm glad I asked instead of silently judging my co-worker for using what I had assumed to be unsanitary salad dressing!
Side note: Spell check just caught that I spelled refrigerator wrong (even though I do know how to spell it, I swear) - but isn't it weird that there is no "d" in refrigerator, yet we shorten the word to "fridge"??
