- two 1/4-ounce packages (5 teaspoons) active dry yeast
- 1 teaspoon sugar
- 2 cups warm water (105°‐115° F.)
- 1 tablespoon table salt
- about 5 1/2 cups all-purpose flour
- 1/3 cup olive oil
- 2 teaspoons minced fresh thyme leaves
- 2 tablespoons cornmeal
- 1/2 cup coarsely grated Parmesan
- coarse salt for sprinkling
- freshly ground black pepper for sprinkling
- In a standing electric mixer fitted with paddle attachment beat together yeast, sugar, and water and let stand 5 minutes, or until foamy. In a bowl stir together table salt and 5 cups flour. Stir oil into yeast mixture. With motor on low speed, gradually add flour mixture to yeast mixture. With dough hook knead dough 2 minutes, or until soft and slightly sticky.
- Transfer dough to a floured surface and knead in enough remaining flour to form a soft but not sticky dough. Form dough into a ball and put in an oiled large bowl, turning to coat. Cover bowl with a kitchen towel and let dough rise in a warm place until doubled in bulk, about 45 minutes.
- Transfer dough to a lightly floured surface and divide in half. Knead thyme into one half and knead plain half 1 minute. Form each half into an oval and invert bowl over them. Let dough rest 5 minutes for easier rolling.
- Preheat oven to 450° F.
- Oil two 13- by 9-inch baking pans and sprinkle each with 1 tablespoon cornmeal. On lightly floured surface with a floured rolling pin roll out dough halves into 13- by 9-inch rectangles and fit into pans. Cover each pan with a kitchen towel and let dough rise in a warm place until doubled in bulk, about 20 minutes.
- Sprinkle plain dough with Parmesan and sprinkle both doughs with coarse salt and pepper. With lightly oiled fingertips make indentations, about 1/2 inch deep and 1 inch apart, all over dough rectangles and bake in middle of oven 12 minutes, or until golden. Remove focaccie from pans and cool on racks.
