Heat a large griddle or cast iron pan over medium heat.
Flatten each tortilla ball with a rolling pin to your desired thinness.
For burrito tortillas, go as thin as you can — the dough should be almost translucent.
For tacos, the dough can be a bit thicker. Cook a few different thicknesses to find your ideal width.
Lay the tortilla on the hot griddle and cook for 10-20 seconds, then flip to the other side to cook for another 10-20 seconds. The tortillas might puff a bit during cooking and become lightly charred in spots, which is desired.
Be careful not to overcook the tortilla or else they will become hard instead of soft and pliable.
Immediately, stack the tortillas in a large cloth or clean kitchen towel to steam and stay warm until you are ready for serving.
