As anyone who seriously celebrates St. Patrick's Day will tell you, the world’s most legendary soda bread comes courtesy of the Emerald Isle. Recipes vary widely between Ireland and the U.S., but traditional soda bread contains soft wheat flour, buttermilk, baking soda, and salt. Dense with a thick crust, this bread has a mild flavor, though in the U.S., bakers like to add raisins, giving it a slight sweetness.
