This sourdough tortilla recipe only requires 5 ingredients, and the dough is a dream to work with!
Place all of the ingredients in the bowl of a stand mixer. Place on the machine and fit with the dough hook. Knead to make a smooth dough, about 5 minutes.
Place the dough in a greased large glass bowl. Turn once to grease the top of the dough. Cover with a lid (or plastic wrap/tea towel) and all to ferment at room temperature for 8-12 hours.
Place the dough on your work surface. Divide into 12 equal pieces. Roll each piece out to a circle that's about ⅛-inch thick. If the tortillas want to stick to your work surface, you can always grease or flour it.
Preheat a cast iron skillet over medium-low heat. Fry the tortillas for about 30-60 on each side, until they begin to turn dark brown in spots. Don't over-cook!
As the tortillas get done cooking, stack them up on a plate.
Serve immediately or store for later use (see note).
Storing: Store in an airtight container at room temperature for up to 3 days. You can also freeze these for longer storage.
