6ouncesFrozen limeade(if you can only find a 12 oz can, let the can defrost a bit, and it will be easy to scoop out the frozen goodness. Or, make a double-batch. SoupAddict won't tell)
3fluid ouncesTequila(get the good stuff; 2010 only comes around once, that's SoupAddict's philosophy)
1fluid ounceGrand Marnier
splashFresh orange juice
splashFresh lime juice
Crushed ice(or, if your blender has an ice crusher setting, then ice cubes will do just fine)
Instructions
Add all ingredients to the blender and blend until smooth and thick.
Notes
*SoupAddict realizes you might be thinking limeade? SoupAddict was likewise skeptical the first time she heard of this, but now much prefers it over a mix. The fact that it's frozen is also a benefit, in SoupAddict's eyes, as it helps the ice stay, well, icy.
