Let's Cook

1. Step 1.

   Whisk masa harina and salt together in medium bowl.

2. Step 2.

   Stir in 2 cups warm water and 2 tablespoons oil with rubber spatula until combined.

3. Step 3.

   Using your hands, knead dough in bowl until it is soft and tacky and has texture of Play-Doh. If necessary, add up to ½ cup more warm water, 1 tablespoon at a time, until proper texture is achieved.

4. Step 4.

   Divide dough into 18 equal portions, about a scant 3 tablespoons (1½ ounces) each.

5. Step 5.

   Roll each portion into smooth ball between your hands. Transfer dough balls to plate and keep covered with damp paper towel.

6. Step 6.

   Cut open seams along sides of 1-gallon zipper-lock bag, leaving bottom seam intact. Spray inside of bag lightly with vegetable oil spray; wipe excess oil spray from bag with paper towel.

7. Step 7.

   Heat remaining 1 teaspoon oil in 12-inch nonstick skillet over medium heat until just smoking. Using tongs, wipe skillet with paper towels.

8. Step 8.

   Place 1 dough ball in center of prepared bag. Fold top layer of plastic over ball. Using clear pie plate, press dough flat into thin 5½-inch circle.

9. Step 9.

   Peel top layer of plastic away from tortilla. Using plastic to lift tortilla from bottom, place exposed side of tortilla in palm of your hand and invert tortilla. Peel away plastic.

10. Step 10.

    Carefully flip tortilla into skillet and cook until bottom begins to brown at edges, about 1 minute.

11. Step 11.

    Using thin spatula, flip tortilla and cook until second side is browned at edges, about 45 seconds.

12. Step 12.

    Flip tortilla again and press center and edges firmly with spatula so tortilla puffs, about 15 seconds.

13. Step 13.

    Transfer cooked tortilla to tortilla warmer or wrap in damp dish towel.

14. Step 14.

    Repeat with remaining dough balls, lightly spraying bag with oil spray and wiping off excess as needed to keep tortillas from sticking.

15. Step 15.

    Serve. (If storing tortillas in damp dish towel, microwave for 2 minutes to rewarm before serving.)
