Some of you know how much I love how food has influenced our culture. This would include our language. For example:
The Cold Shoulder
Believe it or not, there was a time when giving someone the cold shoulder didn’t just mean publicly snubbing them, it actually meant handing them a cold shoulder, as in a cold shoulder of beef. During the Middle Ages, the easiest way to hint to guests that they’d overstayed their welcome was to serve them a heaping mound of cold cow parts. A few platters of nothing but shoulder were supposed to drive away even the most persistent of guests.
