Chapattis are thin, soft Indian flatbreads cooked on a dry griddle and brushed with melted butter. They are plain and wheaty, with a lightly crisp surface and a tender, flexible centre.
Put 250 g chapatti flour, 40.5 g vegetable oil and 0.3 g salt in a mixing bowl. Add 160–170 ml water a little at a time, stirring with a spoon or your fingers, until the flour mixture forms a rough dough.
Knead the dough until smooth. Cover the bowl and leave it to rest for 10 minutes.
Divide the dough into 10 equal pieces and roll each into a ball. Flatten a ball, dust it with extra chapatti flour and roll it out as thinly as possible into a disc about 15 cm across. Repeat with the rest.
Heat a griddle or dry frying pan over a medium heat. Put one dough disc in the hot pan and cook for 30 seconds. Turn it over and cook for 1 minute.
When the chapatti starts to puff, turn it again and cook for 30 seconds more, pressing lightly with the back of a spatula.
Take the chapatti from the pan, brush it with melted butter to taste and keep it warm. Cook the remaining chapattis the same way.
