Grape-Black Cumin Flatbread

Directions

1. 1
   Dissolve yeast in warm water in a large bowl; let stand 5 minutes. Lightly spoon flour into dry measuring cups; level with a knife. Add 2 cups flour and sugar to yeast mixture; stir until well combined. Cover and let stand at room temperature 1 hour to form a sponge (mixture will rise and bubble slightly).
2. 2
   Add 1 cup flour, 1/2 cup cornmeal, 1 tablespoon olive oil, 1/4 teaspoon black cumin seeds, and 1 teaspoon salt to sponge; stir until a soft dough forms. Turn dough out onto a floured surface. Knead until smooth and elastic (about 8 minutes); add enough of the remaining flour, 1 tablespoon at a time, to prevent dough from sticking to hands.
3. 3
   Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, 1 hour or until doubled in size. (Gently press two fingers into dough. If indentation remains, dough has risen enough.) Punch dough down; cover and let rest 5 minutes. Turn dough out onto a lightly floured surface; gently knead in 2/3 cup grape halves. Cover dough with plastic wrap, and let rest for 10 minutes.
4. 4
   Transfer dough onto a baking sheet sprinkled with remaining 1 teaspoon cornmeal. Pat dough into a 14 x 10-inch rectangle; brush with remaining 1 tablespoon olive oil. Cover and let rise 30 minutes or until doubled in size. (Gently press two fingers into dough. If indentation remains, dough has risen enough.)
5. 5
   Preheat oven to 475°.
6. 6
   Uncover dough, and sprinkle with remaining 1/2 teaspoon cumin seeds and kosher salt. Sprinkle remaining 1/3 cup grape halves over dough; gently press into dough.
7. 7
   Bake at 475° for 15 minutes or until lightly browned. Loosen bread from pan with a thin spatula. Serve warm or at room temperature.
