You can freeze the tortillas for up to 3 months (place a small piece of parchment paper in between each tortilla so they are easy to separate once frozen).
Stir all ingredients together in a large bowl and knead until a soft dough forms. Roll the dough into a log that is about 2 inches thick and cut into 8 equal pieces. Roll each piece into a ball and keep them all covered with plastic wrap or a clean cloth until ready to use. If the dough gets too dry and crumbly, kneed in more water and reshape.
Roll each ball between two pieces of parchment paper into 1/8-inch-thick disks (5 to 6 inches in diameter). Alternatively, you can use a tortilla press.
Heat a large cast-iron pan over medium-high heat and cook tortillas until blistered and puffed up, about 1 to 2 minutes on each side.
