A “collins” is a category of cocktail made with a base spirit (typically gin), citrus juice, something sweet, and something bubbly. This on-trend rendition features ultra-popular, slightly smoky mezcal and cucumber.
In a cocktail shaker filled partially with ice, add 1 ounce blanco tequila, 1 ounce mezcal, and 1 ounce fresh lime juice. Shake vigorously, then strain into a chilled Collins glass filled partially with ice. Top with 2 ounces of Fever-Tree cucumber tonic. Garnish with a cucumber slice.
