These are incredibly easy to make and really fun to make with children.
1 1/2 cups all-purpose flour
1/4 teaspoon salt
2 tablespoons butter (or lard, canola or other neutral oil)
1/2 cup warm water
Combine the flour and salt in a bowl and cut the butter in with either two knives or your fingers.
Mix in the water slowly until the dough forms a ball.
Knead on a lightly floured surface, adding flour as necessary, to keep the dough from sticking, 4-5 minutes.
You can wrap the dough in plastic wrap and let it sit at room temperature for several hours, or you can proceed to the next step.
Divide dough into 6 pieces (we can get 8 small ones out of this).
On a lightly floured surface, press each piece of dough into a disk and roll it out as thin as possible.
Heat a large skillet, preferably cast iron, over medium heat.
Cook tortillas until brown spots appear, then turn and cook on the other side, about 4-5 minutes per tortilla.
We like to fill these with beans and cheese, but they'd also be good with regular taco meat or as tostadas.
