Add all ingredients in a large bowl & mix well. Pour all of the buttermilk into the bowl at once and stir using a wooden spoon, just until a soft dough is formed. Knead for a couple of minutes. Divide the dough into 2 portions and shape each into a round loaf pressing the top down a bit to just barely flatten it. Place the loaves on a large ungreased baking sheet. Sprinkle some additional flour on top of each loaf and using a sharp knife, make the sign of a cross in the top of each loaf. Allow loaves to rest for 10 min, bake on the middle oven rack for 40 min or until golden brown.
