In villages around Greece, this classic bread is still baked in outdoor wood-burning ovens. This bread is more dense than other types of bread (the loaf at right measures about 13 inches across and weighs a little more than 2 pounds) and can be made with a variety of flours or a combination of more than one. If you have your own sourdough starter, use 1/2 pound (slightly less than one cup for most starters) in place of the yeast in the recipe. I got this recipe on-line for the ZWT Greece from About.com.
