Dissolve 2/3 tsp. baking soda in 1/2 cup boiling water. Use cup that molasses was measured in, then add to above mixture.

Add 4 cups sifted flour (more if needed) and knead well. Refrigerate for at least one hour. May be kept in refrigerator a few days if desired.

Use confectioners' sugar to roll out instead of flour. Roll out 1/4 to 1/3 inch thick and cut out cookies. Bake in preheated oven at 350 degrees for 8-9 minutes.
