In a large bowl, combine the flour and salt. Cut the butter into the flour mixture using a pastry blender or two knives, until the mixture resembles coarse crumbs.
Add the cold water to the flour mixture and mix until the dough just comes together. Do not over mix.
Turn the dough out onto a lightly floured surface and knead lightly to form a ball. Wrap the dough in plastic wrap and chill in the refrigerator for 30 minutes.
Preheat oven to 400°F. On a lightly floured surface, roll the dough out into a 12-inch circle, about 1/8-inch thick. Cut the dough into 8 wedges.
Place the wedges on a parchment-lined baking sheet. Bake for 15-20 minutes, until golden brown.
Remove from the oven and let cool before serving.
