Put the absinthe and one large cube of ice into a good-size tumbler. Place an Absinthe spoon across the top of the glass with 1 to 2 lump of sugar on it (the Absinthe spoon is a >at spoon with small holes). Now pour water drop by drop on the sugar. The water dropping through the spoon melts the sugar, sweetens the drink, and lowers the alcohol content.
Although absinthe is illegal and no longer available, I have included this drink because there was a time in the nineteenth century when absinthe was the most widely used alcoholic beverage in the world. It was bottled between 131 proof and 150 proof. There is a product called Absente available on the market now that uses a type of wormwood called southwood. Absente is sweeter than the original, and the drip-style preparation might make it too sweet.
