"What's your drink of choice?" Even if you don't watch HBO's "House of the Dragon" you've probably heard of cast member Emma D'Arcy's alcoholic beverage of choice thanks to social media — a Negroni sbagliato, with prosecco in it. The actor who plays Princess Rhaenyra Targaryen appeared in a TikTok video with “Dragon” co-star Olivia Cooke, during which Cooke asked the 30-year-old actor what their drink of choice is. If you're hoping to try out the trending cocktail this weekend, look no further. Campari shared its recipe for the Negroni sbagliato with USA TODAY.
