Ok if you're from somewhere where tortillas are hard to find, or where they are expensive, or where you just can't find the right size... say like Detroit you can make your own with a very simple recipe.

3 cups flour  

2 teaspoons baking powder

1 teaspoon salt

4-6 Tablespoons Vegetable shortening (or Lard)

About 1 1/4 cups warm water

Can of Pan Spray

Flat Pan/ Griddle/ Comal

°Mix dry ingredients in a large bowl

°Add Vegetable Shortening; use a fork to cut in the shortening or use your hands

°Add warm water a little at a time until the dough is soft and not sticky

°Knead the Dough

°Pull off pieces of dough to form about 12 small dough balls; Let them rest for at least 10 minutes

°Using a rolling pin roll them out into flat tortillas; dust the top and bottom with a little flour before rolling.

°Cook them on a flat griddle or in a comal (flat griddle pan) for a few seconds just until the brown specks appear; flip to cook other side. Use small amount of pan spray when needed.

You'll have to do double recipes but it's still pretty easy. Just do the Tortillas one day and the burritos the next day.
