This morning on NPR was a Kitchen Sisters story about Basque Sheepherders. They told us to go to the web site for recipes, including one for bread. I found it at http://www.npr.org/templates/story/story.php?storyId=90914888.
This NPR recipe calls for, among other ingredients, 3 cups of water and 9 1/2 cups ap flour. Later on you are to form it into one ball and bake it in a Dutch oven at 375 for 12 minutes with the lid on, and then 30-35 more minutes without.
