I have to say that I don't like alcohol. So I decided, maybe this cocktail is not so bad, since that's the name. Honestly, not bad. A very interesting combination of flavors.
Squeeze the juice from the grapefruit, dip the edges of the glasses and immediately dip in coarse salt. Finely I do not advise, salt will interrupt the taste. Now pour vodka into the juice, mix, strain and pour into glasses, decorate with a slice.
