Traditional Irish soda bread does not have dried fruit in it, although if you wish, you may add some to this recipe. This is Robert Ditty's recipe; he's widely regarded as the best baker in all of Ireland. His bakery is located in the town of Castledawson in Londonderry.
Preheat the oven to 375 degrees.
Sift together into a large bowl the flour, baking soda, baking powder, salt, and sugar. Add the buttermilk and currants, raisins, or other dried fruit and mix until just combined and a dough forms.
Lightly dust a work surface with flour. Knead the dough for 2 minutes and shape into a round loaf.
Butter an 8-inch pie pan and place the dough inside. Cut a cross along the top and bake for 35-40 minutes. Enjoy warm with butter.
