Winter. This lovely woman you see here is showing me how she makes bread in her backyard oven. A friend is pointing to the aluminum pots baking in the embers underneath the oven floor. This type of bread oven is fired from below. There is a large hole in the floor through which flames rise to lick the oven walls.. Of course, you can’t bake bread with an oven that’s that hot! After the oven comes to temperature, the fire dies down. And when the heat has subsided a little, the bread is loaded into the oven.
