My grandmother was from SONORA, flour tortilla only uses lard, water, salt, no more!, and because my grandmother family was spanish converted jews to christian catholic, they only used olive oil, pork is a dirty thing, a sin thing to eat, so flour Mexican Tortillas now are:FLOUR, VEGETABLE OIL, WATER AND SALT, NO MORE!!!, I LOVE THE EGGS HERE, VERY VERY NICE, GREAT.
