Marshmallows
Soak four ounces of pulverized gum arabic in a teacupful of cold water for two hours. Put into a double boiler with cold water in the outer vessel and bring gradually to the scalding point. When the gum is dissolved, strain through coarse muslin, return to the double boiler with a heaping cupful of powdered sugar, and stir steadily until the mixture is white and stiff. Remove from the fire, beat very hard for a minute and flavor with vanilla; beat a minute longer, and pour into tins, the insides of which have been rubbed with corn-starch. When the paste is cool cut it into squares of uniform size and turn each of these over and over in a mixture made of three parts corn-starch and one part powdered sugar. Keep packed in a tin box until wanted, as they soon dry if exposed to the air.
