(True, edamame isn't exactly Irish, but it is green.)
And sugar cookies for dessert a la Alton Brown's recipe.
Being a lover of brussel sprouts, I was pleasantly surprised to find that the "fried" cabbage tasted like it's little cousins, only less stinky. The colcannon was pretty good, too, but next time I think I'll try boxty - fried potato pancakes sound tasty!
It took me about two hours to make the royal icing and frost the cookies, but the thick, soft, mildly sweet sugar cookie topped with the crisp, sweet frosting is definitely worth repeating. :)
