What are some of your favorite things to mix with liquor?

I’m one of those people who loves the complex, sweet, fruity drinks with five or six different ingredients in them but I also find that when I want something to sip at, I am very happy with a very simple mixed drink with liquor and one or two other ingredients. My absolute favorite thing to mix with any sort of hard liquor is cranberry juice, although I’ve also had lemonade as a mixer and I do enjoy that.

How about you, Jellies. What ingredient is your favorite to mix with liquor?
