Combine all the ingredients except the water in a bowl. Add water, a tbsp at a time, as needed to get the dough to a moist dough consistency (will vary depending on how wet your starter is). It should be slightly wetter and softer than a typical bread dough, and fully hydrated.
Press and fold by pressing down the middle of the dough while pulling the dough on the sides up and folding over. Turn the bowl a quarter turn and continue this process until the dough is homogenous (it will not be perfectly smooth, that is fine!).
Drizzle the sides of the bowl with olive oil to prevent sticking (this is optional but I always do it). Cover loosely and set in a warm place to rise (I use the top of my fridge), at least 6 hours, up to 24 hours. Optional press and folds. You can leave the dough completely untouched, or if you like, perform some press and folds. The press and folds with strengthen the dough and incorporate air which helps the final texture of the naan. It is not a necessary step; because of the long rise time you will still get a great naan bread even with no press and folds. Do whatever works best for you!If making an overnight dough, you could perform one press and fold 30 minutes after mixing up the dough. Let it sit overnight and do another set of press and folds in the morning. If making the dough in the morning. Perform press and folds every 30 minutes (or even once or twice would help) in the first 3 hours of rising. Then leave the dough to proof untouched for the remainder of the day. Separate dough into 6-8 pieces by cutting the dough in half, then dividing each half into 3-4 balls. I find when I let the dough rise overnight I'm more likely to make 8 balls because my dough has risen much more in volume, whereas if I've done a same day dough I tend to make 6 balls. If you like thicker, chewier naan bread, go with 6 balls. If you like thinner, roti style naan, go with 8 balls. Cover with a tea towel to keep moist.
Keep a small bowl of flour beside you for keeping everything well dusted with flour. On a well floured, flat surface, use a rolling pin to roll each piece of dough out into a rough oval shape, until 1/4" thick (thinner than you think - the naan will spring back into itself as it sits and will also puff up alot in the pan). Set aside and cover with a kitchen towel (parchment paper or saran wrap would also work) to keep moist. You can use the kitchen towel as a dividing layer between the next group of naans and repeat until all of your naans are formed and covered. Be sure not to let any naan doughs touch or they will stick to each other.
