This is taken from Camellia Panjabi's "50 Great Curries of India" in which she writes:
The dough for most rotis is fairly standard, as follows:
Dough Mixture
- 1 cup wholemeal flour
 - 1/3 cup warm water
 - 2 tsp ghee or oil
 
Method
- Mix the flour and water together to make a dough, by hand or in a food-processor
 - Then add the ghee or oil
 - Knead by hand for at least 5, preferably 8, minutes as this process will make the
 dough slightly elastic, and the rotis will have a softer texture.
 - For best results, cover with a damp cloth and leave for 1 hour.
 
With this mixture you can make 12 light chapattis or pooris or 6 parathas. These
 should be enough for 3 persons.
