Irish Soda Bread
Martha bakes Irish soda bread using a family recipe from a colleague at the show.
Preheat oven to 375 degrees with a rack set in lower third of oven. Lightly butter a 10-inch round cast-iron skillet; set aside.
In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Add butter, sour cream and egg; mix, using a pastry blender, until mixture resembles coarse crumbs. Stir in raisins, buttermilk, and caraway seeds, if using, and mix until a sticky dough forms.
Turn dough out onto a lightly floured work surface. Using a floured bench scraper, form into a round loaf; using a sharp knife score a large "X" in the center.
Place in prepared skillet and transfer to oven. Bake until loaf is golden brown and a toothpick inserted into the center comes out clean, about 1 hour. If top begins to brown too quickly, loosely cover with a piece of parchment paper-lined aluminum foil. Transfer to a wire rack to cool.
