Simplicity
One of the few drinks I take: Caipirinha.
How ever much sugar you prefer (usually brow sugar, the more coarse kind; I usually take 2 well heaped table spoons), cut a lime into eigths, into a glass, crush until a good amount of lime juice is rendered.
Then add how ever much booze you like in a glass (I ususally take 2 or 3 double shots, so either 8cl or 12cl). Stirr.
Add ice (crushed, or prefered cubes).
Though technicly you should use Cachaça, that works with basicly everything (vodka, rum, tequila, what ever your heart desires).
If it's too strong, let it water down.
Or down it over like 10min max, like I do.
Dosen't need much in terms of prep, just ice, and not much tools (spoon, knife, cutting board, and if you don't like useing your spoon for crushing, something for crushing purposes).
