I meant an old family recipe but that one is a start.
Corned beef Irish style is a very simple dish, cooked in a very simple way. You won't find any elaborate recipes. The recipe I linked you to is by Darina Allen is about as authentic as any you'll find. She collected many old family recipes from elderly people when she was writing her cookbook on traditional Irish food.
I wish you could see the Chicago Irish parade with your own eyes someday:)
Sorry Joker, I'd rather not! As a spectacle in is own right I'm sure it's fine, if you're into that kind of thing, but as an Irish person I find things like dyeing rivers and drinks green weird and cringeworthy.
