What is an absinthe spoon used for?

An absinthe spoon is a long, slotted spoon that is used to add sugar to absinthe. The spoon is placed over a glass of absinthe, and a sugar cube is placed on the spoon. The sugar cube is then slowly dripped with water, which causes it to dissolve and fall into the absinthe. The absinthe is then stirred with the spoon, and the sugar is allowed to dissolve completely.
