3-1/2 cups plus 1 tablespoon all-purpose flour, divided
2 teaspoons salt
1 tablespoon cornmeal or additional flour
In a small bowl, dissolve yeast in water. In a large bowl, mix 3-1/2 cups flour and salt. Using a rubber spatula, stir in yeast mixture to form a soft, sticky dough. Do not knead. Cover and let rise at room temperature 1 hour.
Punch down dough. Turn onto a lightly floured surface; pat into a 9-in. square. Fold square into thirds, forming a 9×3-in. rectangle. Fold rectangle into thirds, forming a 3-in. square. Turn dough over; place in a greased bowl. Cover and let rise at room temperature until almost doubled, about 1 hour.
Punch down dough and repeat folding process. Return dough to bowl; refrigerate, covered, overnight.
Dust bottom of a disposable foil roasting pan with cornmeal. Turn dough onto a floured surface. Knead gently 6-8 times; shape into a 6-in. round loaf. Place in prepared pan; dust top with remaining 1 tablespoon flour. Cover pan and let rise at room temperature until dough expands to a 7-1/2-in. loaf, about 1-1/4 hours.
Preheat oven to 500°. Using a sharp knife, make a slash (1/4 in. deep) across top of loaf. Cover pan tightly with foil. Bake on lowest oven rack 25 minutes.
Reduce oven setting to 450°. Remove foil; bake bread until deep golden brown, 25-30 minutes. Remove loaf to a wire rack to cool.
Mix the cornmeal, flour and a good pinch of sea salt in a large bowl. Stir the yeast into 275ml of warm water, then add to the bowl and mix to form a pliable sticky dough, adding a splash more water, if needed.
On a clean flour-dusted surface, divide into 6 balls, then flatten each into a 10cm round, pushing your fingers into the top to give you a ripple effect. Place on a lightly oiled tray, cover with a clean damp tea towel and leave to prove for 45 minutes.
Working in batches, drizzle a little oil into a large non-stick frying pan on a medium heat. Once hot, cook a few dough rounds for 2 to 3 minutes on each side, or until golden and perfectly charred, then repeat, topping up the oil between batches, if needed.
