In a medium to large bowl, mix the salt into the flour.
Add the butter to the mixture. With your fingers, pinch the cubes into the flour until it disappears. This will take about five minutes.
Add the lesser amount of water the dough and quickly stir together. Add more water, little by little, if the dough isn't coming together.
Put the dough on a lightly floured surface and knead briefly, just until it comes together in a ball. If the dough is too sticky you can add more flour.
Put the dough in a medium bowl to rest. You can add a little bit of oil to help prevent it from sticking. Cover with a towel and let the dough rest for about 30 minutes, which makes the tortillas easier to roll out.
When you're ready to roll out the tortillas, start preheating a large skillet over medium-high heat.
Divide the dough into eight equal sized balls. If you're using a scale, they'll weigh about 57 g each.
On a lightly floured surface roll out the tortillas one at a time. They'll be about 8" in diameter.
Cook each tortilla in an un-greased pan for about 30 seconds on each side. When you see bubbles forming they're ready to flip. Wrap the finished tortillas in a clean towel while you cook the rest.
