Ginger Cookies

1/2 cup molasses
1 tsp. soda
1/4 cup butter
1/4 cup boiling water
2 cups flour
1/2 tsp. salt
1/2 tsp. ginger
1/2 tsp. cinnamon

Stir soda into molasses; melt butter in boiling water. Turn all into a bowl, stir in flour sifted with salt and spices. Add more flour if necessary, but keep dough as soft as can be handled. Roll dough a little at a time, to about 3/8-inch thick. Cut into rounds and bake off in a moderately hot oven.
