The classic French absinthe ritual involves placing a sugar cube on a flat perforated spoon, which rests on the rim of the glass containing a measure or “dose” of absinthe. Iced water is then very slowly dripped on to the sugar cube, which gradually dissolves and drips, along with the water, into the absinthe, causing the green liquor to louche (turbulent in French) into an opaque opalescent white as the essential oils precipitate out of the alcoholic solution. Usually three to four parts water are added to one part of 68% absinthe.
Historically, true absintheurs used to take great care in adding the water, letting it fall drop by single drop onto the sugar cube, and then watching each individual drip cut a milky swathe through the peridot-green absinthe below. Seeing the drink gradually change color was part of its ritualistic attraction. These particular spoons came out of The Café des Promenades in Tonnerre, established in 1880. It was locked and untouched for 41 years until the key was turned in January, 2009. In tin and brass. Ca. 1890 – 1915.
