Watermelon screams summer and sunlight and lazy days by the pool, but watermelon actually has its place any time of year, even at a Los Angeles Christmas cocktail party. Here in Southern California, and I’m sure in many other places (like, say, Mexico), we have a tradition of eating tamales on Christmas. And what would go better with a tamale at a holiday party than a sweet, smoky, spicy cocktail of watermelon juice and mezcal? So basically you can’t go wrong this delicious concoction any time of year.
