, cook it until it reaches an internal temperature of 120°F (49°C). Take it out and let it rest for 1 hour. Then set the oven to 475°F (246°C) and put it back in to sear for about 10 minutes.

Mix the ingredients for bread in a bowl. Knead into a long roll and set onto a baking tray. Let rest, then bake.
