Chapati is a simple thin Indian flatbread made from flour, salt, water and oil. It is soft and pliable, with lightly browned or charred spots from cooking on a hot dry pan.
Combine 450 g wholewheat or plain flour and 5.5 g sea salt in a large mixing bowl.
Add 248 g cold filtered water a little at a time, mixing by hand until a smooth, firm dough forms.
Work in 40.5 g vegetable oil by hand until it is evenly absorbed into the dough.
Cover the bowl with a damp cloth and leave the dough to rest at room temperature for 30 minutes.
Divide the dough into 50 g balls; this should give you 8.
Roll each ball on a lightly floured surface into a round a few millimetres thick.
Heat a tawa or large frying pan until hot; keep it dry.
Cook the chapatis one at a time for about 2 minutes on the first side, then turn and cook for about 2 minutes more, until lightly browned or charred in places.
