How to Make It
Dissolve the dry yeast and 1 tablespoon sugar in warm water in a small bowl, and let stand for 5 minutes.
Place 2 cups all-purpose flour and next 2 ingredients in food processor, and process 30 seconds or until well blended. With processor on, slowly pour yeast mixture through food chute; process until dough forms a ball, leaving sides of bowl. Process an additional 30 seconds. With processor on, drop prunes through food chute; process 20 seconds or until prunes are chopped.
Sprinkle 1 teaspoon flour into a large zip-top heavy-duty plastic bag. Turn dough out into bag. Squeeze air from bag; seal bag, and let rise in a warm place (85°), free from drafts, 40 minutes or until doubled in bulk.
Turn dough out of bag onto a floured surface. Punch dough down; with floured hands, knead 5 or 6 times. Shape dough into a round loaf. Place loaf on a large baking sheet coated with cooking spray. Cover loaf with plastic wrap coated with cooking spray, and let rise 30 minutes or until doubled in bulk. Bake at 375° for 28 minutes or until loaf sounds hollow when tapped, and let cool on a wire rack.
