Of course, the feast day of Saint Patrick is an exception to Lent.
Corned beef was soaked for a couple hours to leech some of the salt out and then marinated overnight in a paste of mustard, pickled serrano peppers, pickled ramps, and garlic, before being slow-roasted this morning. Potatoes, fried. The sauce is smoked pork demiglace, cream, a little whiskey, green peppercorns, and crushed red peppers.
The internet hits the same arguments every year like its own little liturgy, so yeah - corned beef is an Irish-American tradition, not an Irish one; corned beef in the UK is different; and most of those drunk kids out there aren't Irish at all. None of this is a big deal.
