Sour Cobra

Since at least 2960, the Eighth Syrtis Fusiliers have had a traditional drink known as the "Sour Cobra":
Theoretically 2 shots of Bourbon, 1 spoon citrus juice, 1 spoon lemon juice, 1 cup crushed ice. But in reality on New Syrtis they often had to resort to: Bourbon, concentrated citrus or lemon juice, and ice, freshly chopped from a glacier.
The Sour Cobra is also recommended for cleaning purposes.
