Hi,
Just to add to that once you have rolled out the dough to a disc spread the top surface with melted butter or better ghee then roll it up into a thin tube shape as thick as your finger then form it into a spiral before rolling it out to a disc again. Cook adding a small amount of butter to the pan and fry each side for about two minutes until browning in patches.
I must say my parathas are a bit hit and miss as are the ones I buy from the take-away. They can be flaky but sometimes not. There is certainly a technique to their cooking although most recipes I have seen all seem to use the same dough mix.
