Makes approximately 13 tortillas.Pour flour, water, and sourdough starter into bowl.Use enough water to achieve thin glue-like consistency.Let sit covered overnight.In the morning, check consistency (it should still be a bit runny) and add salt and about a spoonful of lard for every cup of flour.Mix.Pour about ⅓ cup onto griddle or pan, pushing the dough out from the center with the back of your measuring cup to flatten into tortilla shape.Flip when somewhat browned or to your liking.Repeat until all of the batter is gone.Fill finished tortillas with meat, beans, lettuce, cheese, salsa, and sour cream for tacos — or use as breakfast burritos with eggs, veggies, and cheese! The possibilities are endless, and the best bit is that time might be a little more on your side now. ;)
