In a large bowl, combine the bread flour, yeast and salt.
Stir the honey into the warm water, then add it to the flour along with the olive oil. Mix until no dry flour remains.
The dough will be sticky. Cover and rest for 20 minutes.
Over the next hour, complete three rounds of stretch-and-folds, leaving about 20 minutes between each round.
Cover and leave at room temperature for 30–60 minutes, just until the dough begins to rise. Refrigerate overnight (12–18 hours).
The next day, remove the dough from the fridge and let it sit for 45–60 minutes. Preheat oven to 220°C (200°C fan)
Generously oil a 23 x 33 cm baking tray. Transfer the dough to the tray and gently stretch it towards the corners. If it resists, let it rest for 10 minutes before stretching again.
Cover and leave to proof for 45–90 minutes, or until light, puffy and bubbly.
Drizzle generously with olive oil. Using your fingertips, press deep dimples across the surface of the dough and sprinkle with flaky sea salt.
Bake at 220°C (200°C fan) for 22–28 minutes, or until deeply golden and crisp.
Cool completely before slicing.
