To prepare flour tortillas: In a large bowl, combine 2-1/2 cups tortilla mix and 1/2 cup water. Stir with a fork until mixture forms a ball, adding additional water if necessary.

Turn onto a lightly floured surface; knead 6-8 times or until smooth and combined. Divide into 10 portions. Roll each piece into an 8-in. circle.

In a 10-in. ungreased nonstick skillet, cook each tortilla over medium-high heat for 30-45 seconds or until bubbles form. Turn tortilla, pressing bubbles down with a spatula. Cook about 30 seconds longer or until lightly browned. Yield: 10 tortillas (8 inches each).
