You've got to try these, they are awesome!
5 c. flour
4 t. baking powder
1 t. salt
1/2 c. shortening
2-3 c. buttermilk (put in 2 to start with and then add a little more if you need some)
Mix all the dry ingredient together then cut in shortening. Add buttermilk. Mix with your hands (or a large wooden spoon if you prefer not to get your hands dirty), kneading the dough as you go. Let sit for 5 minutes, then form dough into balls just a little bit larger than a walnut ( I did mine bigger because I like a larger shell). Let balls rest for 5 minutes. Heat a skillet or griddle...DO NOT add oil. ( I did use a little pan coating, just because...) Roll balls out into a thin tortilla. Place shell in the hot skillet, turn when the shell starts to bubble. Place cooked shell on a plate and serve with your favorite toppings.
* Can use 1/2 wheat and 1/2 white flour if you choose to...I just used white flour.
