I walked right up to an open bar at a wedding in high school and asked for one. The bartender didn't bat an eye. He made me one, and then he made me another, and then ... that was it. I spent the rest of the night dancing away. In college, I discovered the Amaretto Sour, which at the time was made with a cloying, syrupy sour mix. It was like drinking liquid candy. It wasn't until I was much older that I discovered that sour mix didn't have to come in a large plastic jug.

If you can juice some lemons and limes, you can make sour mix. You'll find that different recipes call for different ratios of citrus to simple syrup. I like my drinks with a nice pucker, so I use a ratio of about 1.5-part lemon/lime to 1-part simple syrup. Some people use a ratio of 1:1. It all depends on if you want more sweet or more sour.
