Here is the most frugal tortilla recipe I’ve ever tried. Be sure to let the dough sit for about 30 minutes for easier handling.
4 cups all-purpose flour (or part whole-wheat and part white flours)
1 Tbs baking powder
1 tsp salt
2 Tbs powdered milk
1 ¾–2 cups very warm water
Measure all the dry ingredients into a large bowl and stir until well-combined. Add the water and mix thoroughly. Pour out onto a floured board and knead the dough until smooth and easy to stretch. Form the dough into balls about 1 ½ to 2-inches in diameter, cover with a cloth, and let rest for about 30 minutes. Roll the dough out into thin circles. Cook in a medium-hot skillet (I prefer using a cast-iron skillet) or on a griddle until the tortillas begin to bubble and get lightly-browned. Turn and cook until the other side is also lightly-browned. Remove from the skillet and stack on a plate.
