People know the Mudslide as the quintessential boozy milkshake: sweet, creamy and rich. Its popularity harks back to a time when we took our cocktail cues from the laminated menus of chain restaurants. Which is to say, it’s not generally an exercise in balance and craftsmanship. Most versions are drowned in ice cream and served in circus-size glassware, resulting in a five-digit-calorie cocktail. This Mudslide cuts a bit leaner, showcasing the spirits in place of the brain freeze. If you really want to dress up your Mudslide, swap the vodka for your favorite French brandy.
