DIRECTIONS FOR FREEZING
Pound the ice in a large bag with a mallet, or use an ordinary ice shaver. The finer the ice, the less time it takes to freeze the cream. A four quart freezer will require ten pounds of ice, and a quart and a pint of coarse rock salt. You may pack the freezer with a layer of ice three inches thick, then a layer of salt one inch thick, or mix the ice and salt in the tub and shovel it around the freezer. Before beginning to pack the freezer, turn the crank to see that all the machinery is in working order. Then open the can and turn in the mixture that is to be frozen. Turn the crank slowly and steadily until the mixture begins to freeze, then more rapidly until it is completely frozen. If the freezer is properly packed, it will take fifteen minutes to freeze the mixture. Philadelphia Ice Creams are not good if frozen too quickly.
