Remove dough from refrigerator 30 minutes before shaping to take off the chill.
Generously oil your metal 9x13 inch baking pan with 2-3 tablespoons olive oil.
Turn the cold dough into the oiled pan - it will be very soft and extensible.
Gently stretch dough to fit the pan, creating dimples all over with oiled fingertips.
If dough springs back, let rest 15 minutes and try again.
Cover loosely with a kitchen towel and let rise 45-60 minutes until puffy and jiggly.
Meanwhile, preheat oven to 450°F (230°C) - high heat is essential for proper crust.
Just before baking, dimple the dough all over again with oiled fingertips, creating deep wells.
Drizzle generously with herb oil (about 3 tablespoons), allowing it to pool in the dimples.
Scatter roasted garlic cloves, fresh herb sprigs, and flaky salt over the surface.
Add edible flowers if using.
Bake 25-30 minutes until deep golden brown with crispy edges and internal temperature reaches 200°F (93°C).
Cool in pan for 10 minutes to set the structure.
Transfer to cutting board and drizzle with additional herb oil while still warm.
Sprinkle with more flaky salt and cracked black pepper.
Serve warm with remaining herb oil for dipping.
