Three-ingredient Cocktails for Summer

There's nothing better than a refreshing cocktail by the pool or at a summer cookout, right? Think again! How about a cool, delicious drink that's only three ingredients? Now we're talking! Whether you favor rum, tequila, or opt for something more sophisticated, "The Shine" is giving classic cocktails a modern twist - and each beverage contains three ingredients (plus a garnish, perhaps). Shine's Senior Food Editor Sarah McColl is dishing on her personal favorites. Cheers!
