I have got a margarita mix for you! I just picked up a bottle of Williams-Sonoma Margarita Mixer in Pomegranate-Cherry and it is delicious! Not too sweet or artificial, let's the tequila flavor come through nicely, yet adds just a little flavor to your average margarita. And a salted rim really compliments it as well (pink Himalayan salt looks perfect!). Delicious! And they also have key lime and mango passion fruit. Try 'em here. Not too bad at $15.
