Directions:
Cover sliced pineapples with pure cider vinegar; let them stand three or four days, then mash and strain through a cloth as long as it runs clear; to every three quarts of juice add five pounds of sugar.

Boil it altogether about ten minutes, skim carefully until nothing rises to the surface, take from the fire; when cool, bottle it. Blackberries and raspberries, and, in fact, any kind of highly flavored fruit, is fine; a tablespoonful in a glass of ice-cold water, to drink in warm weather.
