Soft Molasses Cookies

1 cup molasses

1¾ teaspoons soda

1 cup sour milk

½ cup shortening, melted

2 teaspoons ginger

1 teaspoon salt

Flour

Add soda to molasses and beat thoroughly; add milk, shortening, ginger, salt, and flour. Enough flour must be used to make mixture of right consistency to drop easily from spoon. Let stand several hours in a cold place to thoroughly chill. Toss one-half mixture at a time on slightly floured board and roll lightly to one-fourth inch thickness. Shape with a round cutter, first dipped in flour. Bake on a buttered sheet.
