Add flour and salt to a mixing bowl and mix well. Then slowly add the water little bit at a time and mix it in with the flour using finger tips of your dominant hand. Keep adding water and kneading until soft dough (but not sticky) forms. Then add the oil and knead once again for 4 to 5 minutes or until even and smooth dough forms. Cover the dough and allow it to rest for 10 to 15 minutes. Dough can stay at room temperature for an hour or so, or you can refrigerate it in an airtight container for 2 to 3 days.
To make the Dough using Stand Mixer:
Attach the spiral dough hook to the stand mixer. Add flour, salt and 1.5 cups of water to the mixer bowl and start the mixer at speed 2. Add the remaining water as needed. Once the dough has fully formed, add the oil and let the mixer run for another 2 to 3 minutes. Take out the dough, cover it and allow to rest for 10 to 15 minutes. Dough can stay at room temperature for an hour or so, or you can refrigerate it in an airtight container for 2 to 3 days.
Knead the dough once more for a minute and make small round balls from it. With 4 cups of dough you can make roughly 20 balls. Heat the tawa or a shallow pan/griddle on medium heat.
Take one dough ball at a time and roll it in the dry flour so that it is evenly covered with flour. Gently press the dough ball to flatten it and then roll it back and forth using a rolling pin, using gentle pressure. Turn the roti around clockwise a few times, as you roll it evenly on all the sides. Dip it back in flour if it starts to get sticky and form 6 to 8 inch roti.
Gently place the rolled roti on the preheated Tawa and cook for 30 to 45 seconds. Then flip the roti over with a pair of tongs and allow the side touching the tawa to fully cook. About a minute or so, or until the roti starts to get light brown spots over.
Now carefully lift the tawa with one hand (non dominant) and pick up the Roti using the pair of tongs and place it upside down on medium high flame. The Roti will start to pop up, getting brown spots on it, about 20 to 30 seconds. Place the roti in a plate facing up the side that just cooked directly on the flame. Place the tawa back on the flame. Optionally apply ghee or oil, on the top surface of the Roti.
Repeat steps 2, 3 & 4 with remaining dough balls.
Remember that flour to water ratio can vary between different brands and varieties of whole wheat flour. Kneading the perfect dough is pretty much the key step and should be medium soft but not sticky
Leave the dough covered on your counter top for 15-20 minutes before rolling out
While rolling out, start from the center. As the dough rolls out, start rolling more towards the edges. The edges should be flat and thin
Make sure to not put too much pressure while rolling the dough. This may make the fulka thin in parts and hard to puff up
Preheat the pan before placing the rolled out phulka
