2 C white flour
1/2 t salt
1 t baking powder
1/4 C shortening
1/2 C warm water (maybe another 1 T if needed)
Combine flour, salt, and baking powder.
Cut in shortening with a fork
Add milk and mix together. It will look like there is no way it is all going to come together and form a nice ball, but it will. If needed you can add an extra tablespoon of water, but don't overdo it or they'll be too sticky and you won't be able to roll them out properly. You'll need to use your hands to bring all the flour and milk together into a ball.
Cut the dough ball into thirds and then each third in half so that you have 6 little blobs of dough.
Roll them out very thin.
Cook them on a heated, dry skillet. On a pre-heated cast iron pan it takes only 15-30 seconds on each side, but the first couple may take longer if that pan isn't quite heated up.
Place between layers of warm, slightly damp towels to keep them soft and pliable on the dinner table (unless you've actually got one of those tortilla warmer baskets).
