In a large bowl, mix the flour with salt, then add the hot water. Using your hands, keep mixing the dough then knead it until you get a smooth dough ball. What hot water dough is "kill" the flour, which helps create the layers that are flaky and chewy rather than soft and fluffy. Add more flour and cold water as needed. Lightly brush the dough with oil, cover it and let it rest for half an hour (or overnight in the fridge).
