Irish Soda Bread

5 cups all purpose flour
1 cup sugar
1 tablespoon baking powder
1 1/2 teaspoons salt
1 teaspoon baking soda
1/2 cup (1 stick) unsalted butter, cut into cubes, room temperature
2 1/2 cups raisins
3 tablespoons caraway seeds
2 1/2 cups buttermilk
1 large egg

Preheat oven to 350°F. Generously butter heavy ovenproof 10- to 12-inch-diameter skillet with 2- to 2 1/2-inch-high sides. Whisk first 5 ingredients in large bowl to blend. Add butter; using fingertips, rub in until coarse crumbs form. Stir in raisins and caraway seeds. Whisk buttermilk and egg in medium bowl to blend. Add to dough; using wooden spoon, stir just until well incorporated (dough will be very sticky).

Transfer dough to prepared skillet; smooth top, mounding slightly in center. Using small sharp knife dipped into flour, cut 1-inch-deep X in top center of dough. Bake until bread is cooked through and tester inserted into center comes out clean, about 1 hour 15 minutes. Cool bread in skillet 10 minutes. Turn out onto rack and cool completely. (Can be made 1 day ahead. Wrap tightly in foil; store at room temperature.)

Notes: I made 1/2 batch (still a fair-sized loaf!) in an 8-in cast iron skillet, and baked for 1 hour.
