Sift all the dry ingredients at least 2 times.
Make a well in the centre and add all the wet ingredients.
Knead the dough. Knead it for 8-10 minutes until smooth. (See Notes)
Keep the dough in a greased bowl, cover and allow it to proof (rise) for 2 to 3 hours or till gets double, in some warm place. In winters for 3-4 hours. Time is just a rough guide as it varies according to the weather and environmental conditions in your kitchen. Better to keep an eye on the dough, when supple and risen, then it is ready.
Divide the dough into 15-16 parts and make balls.
Again keep these balls covered with a damp cloth for 10-15 minutes. Very important step.
Take a ball, flatten it little, put sesame seeds, nigella seeds(kalonji) and green coriander. Press these with fingers using little oil so that they stick there.
Now, bake these in the oven or cook on the griddle (Tawa) as under.
