Untried
1 cup (227g) sourdough starter, ripe (fed) or discard
1 1/4 cups (283g) water, lukewarm
1/4 cup (50g) olive oil
2 teaspoons instant yeast
1 tablespoon granulated sugar
2 1/2 teaspoons (15g) table salt
2 garlic cloves, finely chopped
1 tablespoon fresh oregano, finely chopped; or 1 1/2 teaspoons dried oregano
4 1/2 to 4 3/4 cups (540g to 570g) King Arthur Unbleached All-Purpose Flour
1/2 to 1 cup (71g to 142g) drained, pitted, and coarsely chopped Kalamata olives
Combine all of the ingredients, except the olives, mixing and kneading to form a smooth dough then fold in the olives.
Cover the dough, and allow it to rise until it's doubled in size, about 90 minutes.
Gently divide the dough in half; it'll deflate somewhat.
Shape each piece of dough into a round loaf. Place each loaf on a lightly greased or parchment-lined baking sheet.
Cover the loaves and let them rise until very puffy, about 1 hour. Towards the end of the rising time, preheat the oven to 425°F.
Spray the loaves with lukewarm water, and make two fairly deep diagonal slashes in each.
Bake the loaves for 25 to 30 minutes, until they're a very deep golden brown. Remove them from the oven, and cool on a rack.
