For the lo-carb drinkers, try this.
In a blender mix the following:
1 1/2 cups tequila (Gold is better)
1 Full shot of fresh squeezed lime juice (The small bitter ones)
2 Teaspoons Lemonade flavor Crystal Light
Fill with ice
Hit the switch
Enjoy!
For the EXPATs who cannot get limeade or drink mixers, the Crystal Light is small and you can bring a lot back with you from your next stateside visit especially if you open all the small tubs and combine them into a large jar. Some of the other flavors make good drinks as well.
