1/3cupsourdough starter(active or discard both work)
Instructions
In a bowl, combine the flour and salt, then add the soft butter and use a fork to incorporate it into the flour until it’s mostly mixed in, with a few small bits remaining; these will fully blend in during kneading.
Add your sourdough starter and enough water to bring everything together into a soft dough.
Knead the dough for about 3 minutes, just until it becomes mostly smooth and the butter is fully incorporated.
Cover the dough and let it rest for at least 30 minutes and up to 4 hours so the gluten can relax and the flour can fully hydrate; if resting longer, the dough will also begin to lightly ferment.
Divide the dough into equal portions and shape each piece into a ball.
Cover the dough balls and let them rest for 15 minutes to relax the gluten again and make rolling easier.
Roll each dough ball into a thin circle, letting it rest a few more minutes if it springs back.
Cook each tortilla on a hot, dry skillet for about 30–60 seconds per side, until bubbles form and light brown spots appear.
Stack the cooked tortillas and keep them covered with a towel to keep them soft and warm.
