Instructions for Homemade Tortilla Shells

1. In a bowl, mix together 2 cups of flour, ½ cup of dry milk powder, and 2 teaspoons of salt.
2. Stir in ¼ cup of water and 2 tablespoons of shortening. Work the dough with your hands until it forms a smooth ball.
3. Place the dough on a lightly floured surface and roll out to 1/8 inch thick.
4. Grease a tortilla press or heavy object such as a book, with cooking spray and place the dough over it. Press gently, so that the dough slightly stretches.
5. Heat a skillet over medium heat and lightly grease with cooking spray. Place the tortilla shells in the hot skillet, cook until slightly golden, 1 - 2 minutes.
6. Cool before serving.
