Blue Milk Cocktail

Liqueur and rum may be omitted for a non-alcoholic version of blue milk.

From wikipedia:
Blue Milk is a drink in Star Wars. In Star Wars Episode II: Attack of the Clones and Star Wars Episode IV: A New Hope, blue milk is shown being served on the Lars moisture farm. Blue milk is, as its somewhat basic name suggests, a dairy drink either naturally or artificially colored blue. The protein-enhanced beverage is served on planets low in natural resources—especially water. Blue milk, coming from the teats of Banthas on Tatooine, is nutritious and has certain medicinal properties.
