From 1894:
Pare two oranges and six lemons as thin us possible, steep them in 1 quart of hot (not boiling) water for four hours. Boil 1 ¼ lb. of loaf sugar in 3 pints of water, skim it, and add to the two liquors the juice of 6 oranges and 12 lemons. Stir well, then strain through a jelly bag, and ice. This will be found a delicious drink.
