2 tablespoons sugar
2 packages active dry yeast
1-8 ounce package barley cereal, uncooked
2 1/2 cups stone-ground cornmeal, preferably white
4 teaspoons salt
4-3/4 cups all-purpose flour

In small bowl, stir sugar and yeast into 1/2 cup warm water, let stand until yeast mixture foams, about 5 minutes.

In large bowl, combine barley cereal, cornmeal, salt, and 4 cups flour. With wooden spoon, stir in yeast mixture and 2 1/2 cups warm water until combined. With floured hands, shape dough into a ball in bowl.

Cover bowl with plastic wrap and let rise in warm place until doubled, about 1 hour.

Punch down dough and turn onto well-floured surface. Knead dough until smooth, about 5 minutes, working in more flour (about 3/4 cup) as necessary while kneading.

Grease large cookie sheet. Cut dough in half and shape each half into a 6-inch round. Coat each round with flour, place on cookie sheet. Cover loaves with towel and let rise in warm place until doubled, about 1 hour.

Preheat oven to 400 degrees F. Bake loaves until golden brown, a total of about 35 minutes, using spray bottle to spritz loaves with water after first 5 minutes of baking, and again 10 minutes later. Cool on wire racks.
