Once you have ordered your Free Books Today, you should celebrate by fixing yourself a delicious Grapefruit Cosmo. This drink is so easy to make and is one of my favorites. I love to serve it in my Lolita I love My Martini Celebration Glass which was a birthday present. The grapefruit juice makes it less sweet than a traditional cosmo made with cranberry cocktail juice. I use fresh-squeezed grapefruit and lime juices and Cointreau to make it perfect for any celebration!
