It's National Margarita Day! Cancel any and all non-alcoholic plans and dust off your blender. (If you don't have a blender, borrow your neighbor's and forget to give it back.) These margarita recipes are for those with adventurous palates, even if their knowledge of Mexican cuisine doesn't extend beyond tacos and burritos. If you drink tequila, you're going to love these recipes. So invite some friends over, bust out that amazing Mariachi record, and get to celebrating National Margarita Day, one of the best fake holidays of the year.
