This recipe is based on the one used by Don D. the longtime owner/operator of the Landmark Gourmet Deli on Pearl Street in lower Manhattan.  Every St Paddy's Day Don would bake up loaves of soda bread.  Every year I'd ask for the recipe.  Nope. The day he learned that his rent was tripling and he would have to be "out" in six months, he wrote the recipe out for me on a brown paper bag (I still have that bag in my recipes binder).  Later that week I made my first Sicilian Soda bread and delivered it to Don.  He approved!
