"Fail Proof" Flour Tortillas - cooking recipe

Ingredients

6 1/2 cups flour
1 1/2 teaspoons baking powder
2 1/2 teaspoons salt
1 cup shortening
2 cups very hot water
butter

Preparation

Mix together dry ingredients.
Cut in shortening.
Stir in two cups very hot water.
On a floured surface, knead the dough for about 2 minutes.
Place in a bowl, cover with a dish towel, and let sit for 30 minutes.
Knead dough and form into balls.
Roll them out as thin and round as possible.
Preheat a griddle or cast-iron skillet.
Slather the skillet with butter -- (yes, I see other people recommend an ungreased baking surface but I like to slather mine with butter).
Cook tortillas one at a time, flipping when a bubble forms.
I then like to slather the cooked tortillas with additional butter because it makes them taste yummy.
