Pour ripe, picked-over raspberries into a carboy, add just enough thrice-distilled vodka to barely cover the berries, and set the jar in the sun. Pour off the vodka after 2–3 days. For ¼ pail vodka, use 3 glasses water and 1½ lbs sugar. Bring the water and sugar to a boil twice, skim until clear, and gradually pour the vodka into the hot syrup, stirring with a spoon. Mix thoroughly and strain through a flannel. Or, strain through a funnel that has been lined with cotton wool, sprinkled with well-pounded coals that have not been slaked with water, and topped with a piece of flannel. Strain the vodka into a carboy in this manner, stopping before the neck of the bottle is filled. Cork the bottle as well as possible and set in a warm place for several weeks until the vodka settles. Then carefully pour off and bottle the clear vodka. If refined vodka is wanted in a short time, add 10–15 grains potash for every quarter-pail of vodka. Dissolve the potash in a wineglass of warm water, mix with the vodka, stirring vigorously, and set in a warm place. Strain as indicated above.
