Made with vodka (or vanilla vodka), elderflower cordial, honey syrup, red chili pepper, and fresh lemon juice. It is designed to offer a sweet sensation at first, followed by citrusy freshness, and to finish with a slight heat of the chili. The recipe was created in 2004/5 by Salvatore Calabrese for his bar Fifty, London, England, which after the usual delays, opened in 2005.
