You mix all the ingredients, and when they are well incorporated shape them with your hands like hamburger patties, if you have a tortilla machine use it to make them in the shape of tortillas, if not you can use a roller, make sure to cover them with a plastic bag first, or you can do ti with your hands, as if you were making tortillas, dont make them to thin though.
