Named after the architectural and urban planner for New York City's Flatiron building, this perfectly constructed cocktail features reposado tequila, cilantro, and fresh watermelon purée. On the menu at The Cellar at Beecher's, it's an ideal sweet and savory summer cooler.
Combine tequila, Cointreau, lime juice, and watermelon purée in a glass. Muddle with a couple leaves of fresh cilantro then shake with ice.
Rim a glass with cilantro salt and pour in the cocktail. Garnish with a skewer of lime slice and watermelon ball.
