These muffins, bursting with tiny sweet currants and a hint of caraway, are the perfect offering for St. Patrick's Day -- particularly if you're looking to celebrate with something other than corned beef and cabbage! This is not at all a traditional Irish soda bread, which would be simply made with whole-wheat flour, baking soda, salt and buttermilk. Thoroughly Americanized, these muffins have traveled a long, long way from their Irish origin -- as have most of us Irish-Americans.
