3 cups flour
1 cup (2 sticks) butter
1/2 cup of water, cold
Place flour in a bowl. Cut butter into small pieces, about pea-size, and place in bowl. Toss around butter pieces, to be sure they are all completely covered in flour. Start to press dough together. This will help determine how much water should be used. My dough was coming together nicely, so I started out by adding only 1/4 cup of water. Then I pressed the dough together, and added just enough water to form a soft, smooth dough.
I was able to keep pressing together all of the scraps of dough and adding some dough that had not been rolled out yet, which allowed me to re-roll numerous times.
