In a medium bowl with a fork lightly mix flour and salt, with a pastry blender cut in the butter until it resembles coarse crumbs. Add cold water 1 tablespoon at a time and mix lightly with a fork after each addition, until the pastry comes together. Shape into a ball with your hands and then refrigerate for 30 minutes. Remove from the fridge and knead softly a few times to soften the dough. Roll dough about a 1/4 inch in thickness, cut into strips, twist the strip a couple of times, place on an ungreased cookie sheet, sprinkle with topping and bake in a pre-heated 180 degree oven for approximately 12-15 minutes. Let cool on cookie rack. Enjoy!
