The Protocol
Preheat oven to 400°F. Roast one head for 35-45 min (soft) and the second for 15-20 min (firm). Mash the soft head into a purée; separate and reserve the firm cloves.
In a large bowl, whisk together all Dry Ingredients, including the optional Dough Conditioners. Ensure even distribution of the black pepper and conditioners.
Add all Wet Ingredients to the dry. Mix until a shaggy dough forms. Incorporate two-thirds of the Parmesan cheese during this stage.
Knead for 6-8 minutes until smooth. In the final 1-2 minutes, gently fold in the semi-roasted whole garlic cloves to keep them intact as large inclusions.
Form into a ball and place in an oiled bowl. Cold Rise (Recommended): Cover and refrigerate for 12-24 hours to develop superior flavor and crumb structure.
Gently divide and shape into ovals or log forms. Place in bannetons or Pullman pans. Cover and proof until the dough has significantly expanded.
Preheat oven (450°F for ovals, 375°F for Pullman). Score ovals and top with remaining Parmesan. Bake ovals with steam; Pullman without. Target internal temp: 195-205°F.
Transfer to a wire rack. Cooling for at least 2 hours is mandatory to set the internal crumb structure and allow the moisture to redistribute.
