This is the cup that I use for measurement
Fill 1 or 2 cups of flour depending upon how many people need to eat
Take 1/2 tablespoon of salt
Take 2 or more cups of water the water levels vary depending upon the batter
The flour and salt with water is mixed and it is mixed well until it is semi solid
After the dough is set you can take some small amount of dough and roll it into flat ones.
Put the chappati in the pan and turn both sides and the chappati is ready
