In a world where the rules don't matter, we've got you covered.
A mix of the finest, most exotic, completely made-up ingredients:
1 cup Unobtanium extract
2 oz of moonbeam
1/4 teaspoon of rare, imported, possibly-non-existent spices
Stir, serve, and pretend you're a sophisticated adult.
For an added touch of class, garnish with a sprig of Unobtanium's patented, totally-not-real, totally-not-boring "Blerg" herb.
See Unobtanium's Unobtanium Extract for more information on the finest, most sought-after ingredients.
