Combining the rich flavors of freshly-grilled tortillas with a slight sourdough tang, you won't eat the store-bought tortillas ever again. They are the perfect vessel for your favorite filling.
Mix all the ingredients in a medium bowl or a bowl of a stand mixer (if you have one). Mix for 5 minutes, by hand or with a dough hook of a stand mixer. If you are mixing by hand, I recommend wetting them with warm water to prevent the dough from sticking too much. You'll get a soft dough that is quite elastic. Transfer it to a bowl.
Cover the dough with a plastic foil or an aluminum foil (to make it almost airtight) and let the dough ferment for 8 - 12 hours at room temperature. I usually ferment for 10 hours, but adjust the proofing time to your home's temperature. Go a little shorter in the summer and a little longer in the winter. You can also cover the dough with a damp tea towel, but make sure it doesn't dry, otherwise, the dough will become drier as well!
When you are ready to cook the tortillas, take the dough out of the bowl and onto a floured surface. Divide it into 10 equal pieces and shape each piece into a ball. Put your pan on the stove and adjust it on medium-high heat to make it hot.
When you have your hot pan ready, roll the first ball of dough out with a rolling pin on a lightly floured work surface (you don't need much flour). Carefully transfer it into a hot pan and cook it for approximately 1:30 minutes on each side. While one tortilla is cooking, roll out the next one and prepare it to cook it. It is normal for the pan to get a bit hotter during the process, so turn it down to medium heat if needed.
Continue until all the tortillas are cooked. Place cooked tortillas on a plate and cover them with a dry tea towel. One of my favorite ways to eat the tortillas is when they are freshly cooked and still extra soft and roll-able (is that a word? If not, we need it).
Notes
You can make the dough up to two days in advance. Simply mix up the dough, let the dough rest at room temperature for 8 hours, and put it in the fridge. Make sure you cover it with something airtight (like plastic wrap or aluminum foil), and it will wait for you to find time to make the tortillas.
If you are not using a fairly non-stick pan, coat it with the oil of your choice (olive oil, coconut oil, etc) to prevent tortillas from sticking to the pan. A cast-iron skillet doesn't need any oil, but you can add some if you'd like.
Roll out the tortillas as thin as you can. They puff up a bit in the pan, so if you want thin tortillas that are easy to roll up, go extra thin!
If you are making this recipe with a stand mixer dough hook, the dough should form a ball after 5 minutes of mixing or so. If the dough does not come together, add a bit more flour. This recipe makes a very soft dough that is pliable enough to form dough balls later for the tortillas.
