In advance, spread about 1/2 pound of quinoa flour evenly on parchment paper on a large baking sheet and bake at 215 °F for 3-4 hours. This will remove any bitterness from the flour.*
In a medium bowl, combine the cup of flour, oil, and salt (if using). Add the warm water, a little at a time, while continuing to mix the flour with your hands. Make sure the liquid is well absorbed before adding more. Mix and knead until a soft and elastic dough forms. You do not need to knead this dough excessively as you would for traditional rotis. Cover and let the dough rest for 20-30 minutes, up to an hour.
Heat a tava, griddle or non-stick (preferably cast iron) skillet to medium to medium-high heat, depending on your stove. You may need to lower the heat after you start making the rotis.
Flour your surface with preferred gluten-free flour. Form the dough into small balls (a bit larger than golf-ball sized), dust both sides with flour, and then use a rolling pin to roll them out into round circles about 6 inches in diameter. Be careful not to apply too much pressure to the rotis while rolling them out. Turn using a spatula and flour them as needed.
Using a large spatula, carefully lift the rolled out roti and place it on the skillet. Let it cook for about 30 seconds or until the bottom sets, then flip and smear it with a bit of oil or butter. Let this cook for 15-20 seconds then flip again, adding more oil or butter, if desired. With practice, this 3rd flip will result in the roti puffing up like normal rotis. Flip a couple more times, while pressing gently, until the roti is completely cooked. Clean the pan with a slightly damp tissue to get rid of excess flour. If you have a gas stove, you can try using the direct heat to let it puff up. Serve immediately.
*Store the roasted quinoa flour in an airtight container in the refrigerator.
