After 1 hour, Preheat the oven to 240 Deg C. One can use a baking stone or baking steel for baking. I am using my Cast Iron Dutch Oven for this.
While preheating keep your dutch oven in the oven covered as shown in the pic.
This will help the dutch oven preheat too.
Once the oven has preheated, Flip the boule on parchment paper, with a chopping board or a pizza peel below.
Score the dough using a Bread Lame. I am using a sharp knife for this.
Now remove the dutch oven, and place the bread. Be careful the oven and the dutch oven is quite hot.
Cover the dutch oven.
Let this bake for 20 minutes initially at 240 Deg C.
Now remove the cover of the dutch oven. Be careful the oven and the dutch oven is quite hot.
Now bake for additional 30 minutes at 240 Deg C. I lowered the temperature to 220 Deg C, as my top was getting too brown.
After 30 minutes your boulle is done. Remove it from the oven.
The bread is done. I also check the internal temperature of the bread after it is done. It should register above 98 Deg C.
Let the bread cool completely for 1-2 hours.
Slice and serve.
