A devilishly good cocktail with a fiery kick, the El Diablo is a lesser-known tequila classic that deserves more time in the spotlight. First appearing in Trader Vic’s 1940s cocktail books, this vibrant drink combines tequila, crème de cassis (a blackcurrant liqueur), fresh lime juice, and a spicy splash of ginger beer. The result? A bold, slightly smoky, and refreshingly tart cocktail with a deep fruity backbone and just enough heat to keep things interesting.
