Cinnamon Apple Pastry

Sift flour and baking soda together. Add butter and rub together till well mixed. With water make a stiff dough. Take a small amount of dough and roll into a rectangular shape twice as long as it is wide (a nice size is 3" x 6") and paper thin. Rub entire surface with your stick of butter, except for a half-inch border on all sides. Spread a thin layer of apples and raisins on buttered area. Mix together the portions of sugar, salt, cinnamon and coriander in a bowl. Spread a generous amount of this mixture over apples, keeping some aside for later. Roll up rectangle of dough with apples, etc. inside. Rub entire pastry with butter. Sprinkle with sugar-spice mixture. Perforate 5 times with a fork and bake at 375 degrees for 35-45 minutes. Makes about 1 dozen.
