Take whole wheat flour in a bowl. Add a bit of water & start mixing.
Add water in small parts while kneading the dough.
The dough should be kneaded until it becomes soft, smooth & pliable. Keep adding the water in small parts until the dough becomes soft & smooth. Keep it for rest for 30 minutes & cover it with a wet cloth.
Now make small balls of dough.
With the help of a rolling board & rolling pin, roll the dough ball into a flat circle. Keep dusting the rolling board & dough ball with whole wheat flour, so it will not become very sticky. Otherwise, the rolled flat dough will crack.
Heat the Tawa (Round Iron Griddle) well in medium flame. Tawa should be hot enough to put the flat round dough circle.
First, cook one side. Cook one-fourth & then turn the other side. After a few seconds, you find the air pocket-forming.
Slowly press the flat side of the bread, so the entire roti gets puffed well. Remove it, add some ghee or butter (Optional) and serve it with the main course.
Notes
Special Note :Chapati or Pulkha preparation differs from region to region. Some people use Whole wheat flour, and some part of the nation uses bajra, jowar, ragi, etc. Some people puff the chapati on Tawa & some uses open fire to puff the Chapati. But the style of making Roti | Chapati | Pulkha is the same all over.
