A recipe from my grandmother, Guadalupa Trujillo Gutierrez
FLOUR TORTILLAS
4 CUPS FLOUR
1/3 CUP SHORTENING
1 TSP SALT
2 TSP BAKING POWDER
1 1/4 CUP WARM WATER
Mix together with pastry cutter or fork the first 4 ingredients
Add the warm water, not hot water, to dry ingredients gradually until soft dough has formed a ball. Let rest 15 minutes. DO NOT over knead it, the ball should be somewhat smooth but doesn't need to be prefect.
Twist off small balls of dough, roll each into a fat little tortilla.
On a cast iron griddle (yes it's better with cast iron) with no oil, brown on medium high heat. The tortilla will start of have "pimples", flip it over and let it lightly cook the other side.
