According to 9 Restaurant mixologist Gennarose, this cocktail with a Sriracha kick can be enjoyed year-round: the spice makes it warming for winter, while the champagne adds a refreshing touch for summer.
In a rocks glass or cocktail shaker, muddle the basil, Sriracha and the two liqueurs.* Fill the glass with ice and top with champagne. Toss back and forth once or twice in another glass or shaker. Serve in a collins glass with the basil garnish.
*Note: Gennarose recommends using a wooden muddler to avoid breaking the glass.
