Blackberry Cordial
Simmer nice ripe blackberries in water enough to cover them, and when they are tender take them out, mash them and strain them through a strong cloth; get all the juice out you can by squeezing, but do not let the pulp and seed come through the bag. Now add a little of the water they were boiled in, however not more than two tablespoonfuls to each pint of strained juice. To every pint of this liquor, add one pound of loaf sugar, one teaspoonful of mace, same of cloves and cinnamon. Boil all these together a few minutes, and strain it again to free it from the spice. When this syrup is cool, add to each pint a wineglass of good French brandy. If you cannot get brandy, substitute rum or whiskey, remembering to use twice as much as you would brandy. This is excellent for children during the prevalence of summer complaints, and an excellent tonic for all debilitated persons.

Blackberry Cordial
To one quart of blackberry juice, add one pound of white sugar, one tablespoonful of cloves, one of allspice, one of cinnamon, and one of nutmeg. Boil all together fifteen minutes; add a wineglass of whiskey, brandy or rum. Bottle while hot, cork tight, and seal. This is almost a specific in diarrhea. One dose, which is a wineglassful for an adult–half that quantity for a child–will often cure diarrhea. It can be taken three or four times a day if the case is severe.

Blackberry Cordial
Mash and strain the blackberries; put the juice on to boil in a brass or bell-metal kettle; skim it well, and to each gallon of juice put three pounds of sugar and a quart of spirits; bruise some cloves and put in. This is valuable as a medicine for children in summer.
