This is a delicious twist on the traditional Irish Soda Bread, that omits the "soda" entirely and substitutes sour cream for the traditional buttermilk. I think it makes the loaf more moist, sweet and delicious. It has become my favorite version. My husband got it from a colleague, whose great-grandmother (Mary Moriarty, born in Killarney, County Kerry, Ireland in 1902) handed it down to her. Bravo Mary Moriarty!
