Peel 1 or 2 large Cucumbers, cut them into slices, and place them in a double boiler, which should be closely
covered. Cook them slowly until they are soft. Then put the pieces into a fine linen bag and squeeze them until all
the juice has been extracted. Add to the extracted juice one-fourth of rectified spirits of wine (or whiskey) and one third
of Elder-flower water. Shake the mixture well and pour into small bottles ready for use.
