In a small bowl, combine the warm water, yeast and sugar. Let sit for 5 minutes, or until it has begin to foam.
Add the yeast mixture to a mixer bowl then add in the oil, salt, and 2 cups flour. Using the paddle attachment, blend until mixed well.
Stir in enough remaining flour to form a stiff dough.
Remove the paddle attachment and add the dough hook - allow to “knead” for 5-8 minutes.
Alternatively, turn onto a floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl, turning once to grease top.
Cover and let rise in a warm place until doubled, about 1 hour.
Punch dough down. Turn onto a lightly floured surface.
Shape into a 16x2-1/2-in. loaf. Or you can shape into two smaller loaves.
Sprinkle cornmeal over a greased baking sheet; place loaf on baking sheet.
Make three diagonal cuts across the top. Cover lightly with a towel. Let rise for 30-60 minutes
Once the dough has risen, preheat oven to 375°.
Beat egg white and cold water; brush over dough.
Bake until golden brown, 25-30 minutes.
Remove from pan to a wire rack to cool.
