Divide the dough into 4 equal balls. Dust a work surface with flour and roll one of the balls out as thinly as possible. Brush the top with butter, sprinkle over some nigella seeds and Maldon salt, then roll the circle up to create a tight sausage. Coil the tube in on itself to create a spiral shape, tucking the end underneath itself, then roll out until thin. Brush with butter, roll into a sausage, coil into a spiral and roll flat once again, then repeat this step for a final third time until you’re left with a thin flatbread. Set aside under a tea towel and repeat with the remaining three balls of dough to create 4 flatbreads
