The method
- 01
Mix flour, water, yeast and salt to a shaggy dough. No kneading.
- 02
Fold the dough in the bowl four times, 30 minutes apart, then refrigerate 8–24 hours.
- 03
Oil a pan generously, tip the dough in and let it relax at room temperature for 2 hours.
- 04
Dimple all the way to the base with oiled fingers, pour over more oil, scatter rosemary and flaky salt.
- 05
Bake at 450°F for 22–25 minutes until deep gold and hollow-sounding. Cool on a rack so the base stays crisp.
