Shape two rolls so it will be easier to measure out equal balls.
Cut the rolls into equal pieces.
Form balls.
Place a ball between two layers of plastic sheet.
Press it down with a dish. There are special tortilla pressers out there to buy too!
Heat a cast iron skillet to medium high then flip a tortilla on it. We first need to seal the tortilla both sides and then cook it. At the right temperature the whole process takes about 80 seconds, twice 20 seconds each side.
Depending on the heat, in about 20 seconds flip the tortilla to the other side. If it has big burnt batches already then take the heat down a notch. We may see some air pocket coming up at this stage, that's normal and the sign of a good tortilla.
After about 20 seconds, flip it again then wait 20 seconds more and flip it again for the last 20 seconds.
Cover the tortillas with a kitchen cloth. The top ones are a bit crispy but the ones at the bottom are ready to be filled. Freeze the leftover so there are always backup tortillas ready to be filled.
