Melt half a pound of butter in a pint of warm milk, adding a tea-spoonful of soda; and stir in by degrees half a pound of sugar. Then sift into a pan two pounds of flour; make a hole in the middle; pour in the milk, etc, and mix it with the flour into a dough. Put it on your paste-board, and knead it long and hard till it becomes very light. Roll it out into a sheet half an inch thick. Cut it into little round cakes with the top of a wine glass, or with a un cutter of that size; prick the tops; lay them on tins sprinkled with flour, or in shallow iron pans; and bake them of a light brown in a quick oven; they will be done in a few minutes. These biscuits keep very well.
