Place sugar, water, and yeast in the bowl of a mixer and mix lightly. Then, add the oil, salt, and 2½ cups of flour to the bowl. Mix dough until mostly combined.
Add 1 ¼ cups of flour and allow it to mix in. Then, continue to add flour ( up to ¼ cup) just until the dough stops sticking to the bottom of the bowl. Increase the speed of the mixer to 2 and knead dough for about 8 minutes.
Place dough ball into a lightly oiled bowl, coating each side. Cover the bowl lightly and allow the dough to rise for 1 ½ hours, or until it has doubled in size.
Punch down dough, then re-cover and let it rise for an additional ½ hour.
Place a pizza stone or an inverted baking sheet in the oven, then preheat the oven to 375°F. If you have a pizza paddle, sprinkle it with cornmeal. If you don't, line a rimless baking sheet with parchment paper, then sprinkle it with cornmeal.
Divide the dough in two and gently roll each between your hands until they're approximately 10 inches long and tapered at the ends. Place the loaves on either the pizza paddle or baking sheet. Then, allow the dough to rise for ½ hour, uncovered.
Prepare the egg wash by beating together the water and egg white. Brush the tops and sides of the loaves with the egg wash.
Slide loaves onto the heated pizza stone or baking sheet (without the parchment paper) and cook for 25 minutes, until loaves are golden brown.
If you are not eating the bread immediately, allow the loaves to cool completely before storing. Use bread within 2-3 days or freeze in an airtight container.
