This cocktail from Hailey Knight and Casey Knight (no relation) of Charleston's Félix Cocktails et Cuisine takes the spicy Margarita for an extra-savory spin. Saline lends a saltiness, while Lillet Blanc rounds out the edges of the fresh lime juice. Meanwhile, Knight recommends using your favorite hot sauce to spice it up. "The key is to use a vinegar-based hot sauce to complement the cocktail’s flavors rather than compete with them," she says. "I’m partial to Slap Ya Mama hot sauce."
