Grandma Rose's Flour Tortillas

4 cups flour
2 teaspoons salt
1 teaspoon baking powder
1/3 cup shortening
1 1/4 cup warm water

Mix until sticky. Pinch off balls, roll in hands into balls. Let dough rest while you heat the skillet until hot, then turn the heat down to low. Roll each ball out until round and thin. Place on griddle or fry pan, cook on both sides. If want to use them later, place in plastic bag to steam.
