Combine the flour and salt, and cut in the suet with a knife until fine particles. Add the warm water gradually, and toss with fork to make a stiff dough.
Knead thoroughly on a lightly floured surface until smooth and flecked with air bubbles. Divide dough into 8 balls and roll as thinly as possible.
Place a plate on the rolled out piece of dough and use a knife to score round the plate. Add the surplus dough back with the rest.
Drop onto a very hot ungreased cast iron skillet or griddle and cook for about 30 seconds on each side. Repeat with remaining tortillas. Use at once, or wrap tightly and refrigerated or frozen.
Once you've made these and realize how EASY they are you will never buy store tortillas again. The taste is out of this world!

2 cups all-purpose flour
1 teaspoon salt
1/4 cup vegetarian suet (DO NOT use margarine or anything else, it doesn't work)
