I can't say it enough. Practice as many times as you can to achieve the tortilla you are happy with! If you don't want to add shortening or lard to your recipes, you can substitute with coconut oil, olive oil or corn oil. Manteca(lard) and Shortening works the best for me. There is always a big controversy when it comes to adding baking powder to the recipe. Honestly, I don't remember mom ever adding baking powder to her tortillas. I have experimented with and without it. I have had different results depending on where I am in the country, lol! I truly believe that the atmosphere where you are plays a big part in how your tortillas will turn out.
