Auntie Vicenta's Flour Tortillas

In a bowl, cut in shortening with a fork:
2 cups flour
pinch salt
3/8 cup solid vegetable shortening, (like Crisco™) (originally lard)

Add warm water mixture a little at a time, until dough is pliable. Depending on the humidity and flour, you may only use 3/4 cup total:

7/8 cup warm water
1/8 cup milk
Knead until elastic, then roll pieces into rounds the size of golf balls and place on a towel.
Cover with another towel.
Let set for at least 30 minutes.
Heat griddle.
Roll into nice thin rounds. Place on hot griddle; when bubbles form, flip the tortilla and cook on the other side.
Stack tortillas on a towel.
Makes 15-20.
Serve warm with butter or use for "roll your own burritos" or "soft tacos."
