In a large mixing bowl, combine 2 cups flour, yeast, sugar, salt, and baking soda. Add warm milk and water; beat on low speed for 30 seconds, scraping bowl occasionally. Beat on high for 3 minutes. (or mix by hand…) Stir in remaining flour (batter will be stiff). Do not knead. Grease two loaf pans. Sprinkle pans with cornmeal. Spoon batter into the pans and sprinkle cornmeal on top. Cover and let rise in a warm place until doubled, about 45 minutes. Bake at 375 degrees for 35 minutes or golden brown. Remove – slice – toast – enjoy!
