Make traditional Irish soda bread by mixing together 3 cups of flour, 1 tablespoon of baking powder, 1 teaspoon of baking soda, 1 teaspoon of salt and 1/3 cup of white sugar. Whisk together 1 egg and 2 cups of buttermilk, and mix the liquid into the flour mixture. Fold in 1/4 cup of melted butter, and pour the batter into a loaf pan. Bake the bread at 325 degrees Fahrenheit for 15 minutes.
To make another traditional recipe, blend together 4 cups of all-purpose flour, 4 tablespoons of sugar, 1 teaspoon of baking soda and 1 1/2 teaspoons of kosher salt in a bowl, and then beat in 4 tablespoons of cold unsalted butter at low speed. In a separate bowl, lightly whisk together 1 extra-large egg, 1 3/4 cups of cold buttermilk and 1 teaspoon of grated orange zest. Drizzle the wet ingredients into the flour mixture, mixing the entire time. Toss 1 cup of dried currants with 1 tablespoons of flour, and fold them into the dough.
Knead the bread dough on a floured surface, forming in into a loaf, and place the loaf on a sheet pan. Cut a shallow X on the surface of the dough, and bake it at 375 degrees Fahrenheit for 45 to 55 minutes.
