Firstly take a large mixing bowl and add 2 cups of refined flour in it.
Add 1/2 tablespoon of carrom seeds in it.
Add 1/2 tablespoon of black cumin in it.
Add salt as per taste.
Finally add 1/2 cup of desi ghee in the bowl.
Mix and Knead it well with your hands.
Make sure the desi ghee gets absorbed evenly. It should resemble bread crumbs.
Now hold a dough in your fist, if it forms a lump and does not crumble, your dough is ready for the next step.
Now slowly add 8 to 10 spoons of water to bind the flour.
You must keep in mind that you are just adding water to mix the dough with water and not to knead it like a roti. (TIP:Add very little amount of water and that to slowly and one by one)
The dough must be firm and not soft, once done, let it rest for 20 minutes.
