It is a favorite drink in Sweden and Russia.
The active part of the genuine Benedictine cordial is composed nearly exclusively of plants growing on the steep precipices of Normandy; they are gathered and infused at the time when the sap rises, and the blossoms spring forth. These herbs, growing near the sea, are saturated with bromine, iodine, and chlo-ruret of sodium, and develop and keep their healing power in the alcoholic liquids; only best cognac is used for infusion.
Peel twelve bitter oranges, infuse the rind with one quart of old Jamaica rum or arrack de Batavia in a well-covered tureen for twenty-four hours; strain the fluid, and fill it into small bottles, cork, and seal.

The preparation of this famous cordial and its trade is monopolized by the monks of the monastery Grande Chartreuse, in the French departement Isere; the monastery was built by St. Bruno in the year 1086.
The monks keep their secret very carefully; an imitation may be obtained in the following way: Take one pint of the best brandy or kirschwasser, eight drops of vermouth essence, one drop of cinnamon essence, one drop of rose essence, and twelve ounces of sugar that was refined and cleared in one pint of water; strain through flannel, cork, seal, and let it lie at least eight weeks.
