Ingredients

2 1/4 teaspoons active dry yeast
2 cups warm water (110 degrees F/45 degrees C)
1 tablespoon white sugar
1 tablespoon salt
8 cups all-purpose flour
1 tablespoon cornmeal
1 tablespoon sesame seeds (optional)
2 tablespoons cold water

Preparation

In a large bowl dissolve the yeast in the warm water or potato water. Add sugar and salt and mix well. Stir in 7 cups of the flour.
On a well-floured surface, knead dough for 7 minutes, incorporating in the last cup of flour. Place dough in a greased bowl. Let rise until doubled.
Using a lightly floured board, form dough into 2 long or round loaves. Sprinkle cornmeal on greased baking sheet; place loaves on top. Slash top with a sharp knife. Cover, and let rise until almost doubled.
Brush top of loaves with cold water. Sprinkle with sesame seeds, if desired. Place in a cold oven.
Turn oven to 400 degrees F (200 degrees C). Bake for 45 minutes, or until nicely browned. Brush twice during baking time with cold water.
