Salmiakki koskenkorva
Salmiakki Koskenkorva, is a pre-mixed liqueur popular in Finland. Traditionally, the cocktail consisted of Koskenkorva Viina vodka with salmiakki extract dissolved into it. Sometimes, ground-up Tyrkisk Peber is used instead of the extract. Salmiakki Koskenkorva is a somewhat viscous black liquid, or a dark grayish brown when of a thinner consistency. Upon closer inspection, very fine particles of carbon black are visibly suspended in the liquid.
