But rather than have to declare your alcohol allegiance, it's possible to combine the cocktails of these two unofficial holidays -- if you don't mind a major culture clash -- and toast them with a Mint Margarita.[jump]
There are numerous mint margarita recipes; this one comes from the August 2008 issue of O, The Oprah Magazine:
Fresh Mint Margaritas
Ingredients 1/2 cup chopped mint leaves 1/2 tsp. kosher salt 4 cups crushed ice 1 1/2 cups good-quality tequila 1 cup freshly squeezed lime juice (from about 8 limes) 1 cup Triple Sec
Directions In the bottom of a large (2-quart) pitcher, crush together mint and salt, pressing with the back of a wooden spoon. Add ice. Add tequila, lime juice, and Triple Sec, stirring vigorously. Serve in short tumblers or wineglasses.
Optional: Try to use the leaves of mint "margarita," a perennial in the mentha species that officially merges the two traditions.
