Instructions: In a food processor, place 1 stick of butter, 1 teaspoon salt, and 2 1/2 cups flour and blend until texture of breadcrumbs. Slowly add ice water until dough comes together. Remove and form into a ball, then flatten it into a 8- by 10-inch rectangle and place in refrigerator. This is called the pasta mixture.

In a food processor, place 3 remaining sticks of butter and 1 cup four until blended and scrape out on to a board. Working quickly, form this mixture in a 4-inch square and place in refrigerator. This is called the burro mixture.

After 1/2 hour, when the two mixtures are similar in texture, place pasta mixture on a well-floured clean marble surface. Place burro mixture in center and fold the pasta mixture over it, like wrapping a gift. Flatten with a rolling pin and roll out to a 8- by 16-inch rectangle, flouring regularly. If butter comes to surface, flour the spot heavily and continue working. Fold bottom third up and top third down to form a small package and turn one quarter clockwise. Pat dough with rolling pin to adhere and roll out to large 8-inch by 16-inch rectangle again. Repeat folding process and refrigerate 30 minutes, covered in a moist cloth. Remove and repeat the rolling-and-folding process 3 times. Allow 30 minutes refrigeration between each maneuver. The dough is now ready and will keep in the refrigerator 10 days, wrapped tightly in plastic wrap.

This recipe yields enough dough for 4 servings.
