Growing up in hot summers, our drive-in soda treat was a cherry limeade. Still to this day, I can pop through a local drive-through in my home town and get a huge styrofoam cup with filled with soda, a squirt of 7-Up, cherry syrup and fresh squeezed limes. I figured it was time to make this a grown up treat and voila' -- fresh limes, simple syrup, soda water, and pomegranate liquor. Crushed ice is a must. Perfect!
