Makes 2 dough rounds, enough for 1 pie or 2 galettes or tarts
Mix flour, salt, and cold water in a bowl and combine. Add the butter and incorporate into the flour. Add water if necessary. Turn out onto your work surface, shape into a 5” square, and cover with plastic wrap and refrigerate for 30 minutes.
After the dough has rested, take out of the refrigerator set onto your work surface. Roll out into a rectangle measuring 12” x 6.” With the shorter side nearest you, fold the dough up a third of the way, then fold the top down onto the side that was just folded up, much like a letter. Rotate 90 degrees, the roll out to 12” long. Fold once more, then cover with plastic wrap and refrigerate. Let dough rest for 30 minutes.
Repeat 2 more times. Let the dough fully rest for 1 hour in the refrigerator before using for a recipe.
