Bourbon • Sour
The Cascabel

Inspired by the Rattlesnake (a classic whiskey drink from the Savoy Cocktail Book), this cocktail from B.S Taqueria in Los Angeles is a smoky, spicy, frothy mix of maple syrup, bourbon, lemon juice, egg whites and Ancho Reyes (a chile liqueur). A few drops of Peychaud’s bitters dashed on top play up the spice and tame the maple syrup’s sweetness.
