Put the flour in a medium bowl and rub in the oil with your fingertips. Stir in 225ml warm water, mix thoroughly, then knead until the dough feels smooth and elastic.
Put the dough onto a lightly floured surface and divide into eight balls. Sprinkle the work surface with a little more flour and roll out one of the balls very thinly, using a floured rolling pin, to around 22cm in diameter. Turn the dough regularly and sprinkle with a little more flour if it begins to stick. Set aside and make the other flatbreads in the same way. If making ahead, freeze before cooking.
Put a medium non-stick frying pan over a high heat and, once hot, add one of the flatbreads. Cook for about 30 secs, then turn over and cook on the other side for 30 secs. Press the flatbread with a spatula while cooking to encourage it to puff up and cook inside – it should be lightly browned in patches and look fairly dry, without being crisp. Repeat with the remaining flatbreads, keeping them warm by wrapping in a clean tea towel until needed.
