Via this post, the Virginia origins of "chitlins" are explained on this page, which begins: "In colonial Virginia, December was the time that hogs were slaughtered."
While my grandparents raised pigs outside of Christiansburg, we literally ate "high on the hog." The tenderloin and shoulder meat were great stuff, and the rest I have blocked out of my mind. Any excuse to recollect the food at their house is a good one.
I have often told the story of eating there twice on the day of the Virginia-Virginia Tech football game in 1984 (the game of the fourth down pass to John Ford) when my college roommates, those suave and debonair cosmopolitans, decided the best plan after the game was to go back and eat more at Grandma's house.
