Mix flour, yeast, salt & sugar in a bowl
Add water and knead 5–7 minutes until smooth and elastic
Let the dough rise covered at room temperature until clearly doubled (60–90 minutes)
Divide dough into 9 equal pieces
Shape into tight, smooth balls and place on baking paper, seam side down
Rest 15–20 minutes, lightly covered
Using a very sharp knife or razor, score each roll once in the center, about 1 cm deep, at a 30° angle
Preheat oven to 250 °C / 480 °F with an empty metal baking tray on the bottom rack
Pour ½ cup hot water onto the hot tray and immediately close the oven door
Bake 10 minutes at 250 °C / 480 °F
Reduce to 230 °C / 445 °F and bake another 10–12 minutes until deep golden brown
Let cool at least 10 minutes before cutting
