Ingredients

  • 1 package (2 1/2 teaspoons) active dry yeast
  • 1/4 cup warm (105 to 110 degrees F) water
  • 2 tablespoons extra virgin olive oil
  • 1 1/2 teaspoons salt
  • 3/4 teaspoon coarsely cracked black pepper
  • 3 1/2 cups bread or unbleached all-purpose flour, approximately
  • 4 ounces (1/4-inch thick) sliced prosciutto, chopped into 1/4-inch dice
  • 1 1/2 tablespoons chopped fresh rosemary or 2 teaspoons dried rosemary

Method

  • In a large bowl or in the bowl of a heavy-duty electric mixer, sprinkle the yeast over the water and stir.
  • Let stand until the yeast softens, about 10 minutes.
  • Stir to dissolve the yeast.
  • Using a wooden spoon or the paddle blade of the mixer, stir in the oil, salt and pepper.
  • Gradually beat in enough flour to make a shaggy dough that clears the sides of the bowl.
  • If kneading by hand, turn out the dough onto a lightly floured work surface.
  • Knead the dough, adding more flour as needed, until the dough is smooth and elastic, about 10 minutes.
  • If kneading by machine, change to the dough hook and knead on medium-low speed until the dough is smooth and elastic, about 8 minutes.
  • If desired, knead on the work surface to check the consistency.
  • Shape the dough into a ball.
  • Transfer the dough to a lightly oiled large bowl.
  • Turn to coat the dough with oil.
  • Cover tightly with plastic wrap.
  • Let stand in a warm place until doubled in volume, about 1 hour.
  • Punch down the dough and shape into a ball.
  • Return the dough to the bowl, turn to coat with oil, cover and let rise until doubled again, about 45 minutes.
  • Position a rack in the center of the oven and pre-heat to 400 degrees F. Lightly oil a large baking sheet.
  • Turn out the dough onto the work surface.
  • Knead, gradually working in the prosciutto and rosemary.
  • Flatten the dough into a 12-inch disk.
  • Starting at a long end, roll up jelly-roll style.
  • Pinch the seams shut.
  • Place on a baking sheet, seam side down.
  • Cover loosely with plastic wrap.
  • Let rise until doubled in volume, about 30 minutes.
  • Using a very sharp knife, cut 3 shallow diagonal slashes in the top of the bread.
  • Bake until the bread is golden brown and sounds hollow when tapped on the bottom, 35 to 40 minutes.
  • Cool completely on a wire rack.
  • If desired, wrap in aluminum foil and store at room temperature up to 8 hours before serving.
