Shape the dough into a ball, put it in a bowl lightly coated in olive oil. Cover with cling film coated with some more olive oil, and leave to rest for 20 minutes.
Remove the dough from the bowl and keep the cling film for later. Stretch the dough by hand to make a rectangle about the same size as your baking tin or tray and then fold it over on itself 3 to 4 times. This step should give the bread its familiar soft chewy texture.
Put a thin coat of olive oil on your baking tray. Place the dough in the middle of the tray, and cover with the same cling film used earlier. Put it somewhere warm and leave to prove for 90 minutes, or until doubled in size.
Stretch the dough to cover your baking tray, scatter over most of the sea salt flakes and leave to rest for 30 minutes.
Use your fingertips to press down all over the dough to create small holes all over.
Mix the glaze ingredients and drizzle over the bread filling in all the small holes and add the rest of the sea salt flakes.
Heat the oven to 220C/200C fan/gas 7 and rest the dough for a further 20 minutes.Bake the bread for 20 to 25 minutes, until golden. Remove from the oven and let it cool for 5 to 10 minutes before transferring it to a cooling rack.
