I attended a talk on Irish traditions and culture at my library not too long ago. One thing I learned, and rejoiced in learning since I don’t like the taste, was that you shouldn’t eat corn beef and cabbage on St. Patrick’s Day if you want to honor or experience Irish culture.
When the Irish immigrated to the US during the Potato Famine, they were poor. The only food they could afford was corn beef. So eat lamb or pork, which Irish typically ate in Irish.
I learned from this website that corned beef was eaten by kings as a way to drive the “demon of gluttony” out of his belly. As someone who doesn’t like the taste of corn beef and cabbage, I understand how that ancient practice could work.
