To each quart of raspberries allow a pound of loaf-sugar. Mash the raspberries and strew the sugar over them, having first pounded it slightly, or cracked it with the rolling-pin. Let the raspberries and sugar set till next day, keeping them well covered, then put them in a thin linen bag and squeeze out the juice with your hands. To every pint of juice allow a quart of double-rectified whiskey. Cork it well, and set it away for use. It will be ready in a few days.
Raspberry Vinegar (which, mixed with water, is a pleasant and cooling beverage in warm weather) is made exactly in the same manner as the cordial, only substituting the best white vinegar for the whiskey.
