Pour the water into a small bowl and refrigerate.
Sift the salt and flour together into a large bowl. Set aside.
Place 10 ounces of soft butter between 2 sheets of plastic wrap. Use your hands and a rolling pin to form the butter into a 5-inch square. Wrap tightly in plastic wrap and refrigerate.
Take the remaining 3 ounces of softened butter and pinch it into the flour-salt mixture in the bowl. When the texture resembles cornmeal, dig a well in the center and add the refrigerated water.
Using your hands, mix the ingredients until they form a coarse dough ball.
Place the dough on a lightly floured surface, and knead it a few times until smooth. Wrap the ball tightly in plastic wrap and refrigerate.
When the butter and dough have reached the same level of firmness, remove both from the refrigerator.
Using a floured rolling pin, roll the dough ball into a square on a lightly floured surface. Place the butter square in the center of the dough square, then rotate the butter 45 degrees so that the four corners of the dough are exposed.
Fold the dough corners over the butter, encasing the butter entirely in a dough envelope. Use a pastry brush to dust away any loose flour on the dough as you work.
Using a rolling pin, gently roll the envelope into a rectangle.
Fold the rectangle into thirds lengthwise, like a business letter. Wrap tightly in plastic wrap and refrigerate for at least 1 hour.
Once the dough is completely cold, remove from the refrigerator and unwrap. Then, starting from the short end, roll into a rectangle again.
Fold the dough into thirds lengthwise, wrap it in plastic, and refrigerate a second time. Continue to fold, wrap and refrigerate three more times, for a total of five cycles.
After the fifth refrigeration, your dough is ready to use. Defrost the frozen dough in the refrigerator before using.
Note: The dough will keep in the refrigerator up to 3 days and in the freezer for 1 month.
1 tsp. salt
13 oz. (about 3 cups) all-purpose flour
13 oz. (1 pack plus 10 Tbsp.) unsalted European butter, softened and divided
