An easy, refreshing summertime drink that tastes good with or without alcohol.
The Mojito is a delicious Cuban drink that's been around for at least several decades. Ernest Hemingway liked Mojitos, but they were probably only tangentially related to his eventual suicide. Here's about as official a recipe as you can get:

-- though other recipes call for actually boiling up a "sugar syrup" instead of just adding sugar.
Now I'm going to offer you a slightly easier recipe of my own devising. I have tested it many, many times to be sure it is fit for my BYOND friends to drink.
Ingredients:
1/2 lime
about 12 mint leaves (check your local grocer's produce section)
1 12-oz. can 7UP (diet 7UP and Sprite also work well)
Squeeze as much juice as you can from the 1/2 lime. Add the mint leaves to the juice. Dent and crush the leaves with the edge and back of a spoon for a minute or so (this is called "muddling" and it releases the mint flavor). Pour in the full can of pop.
A Mojito without alcohol is called a "virgin Mojito." Older BYONDers can add a shot of light rum before muddling the leaves.
That's it! Enjoy!
