I found this recipe on liquor.com.
gin, vodka, Lillet Blanc
Mine is blue because I used Empress Gin.
The Vesper was first mention (and invented) by James Bond author Ian Fleming. It first appeared in the book Casino Royale, and is named after the character Vesper Lynd.
This deffo has a martini vibe – sort of a cross between a gin martini (which is so boozy that it’s kind of hard for me to drink) and a vodka martini (which doesn’t really taste like anything to me). It’s a nice halfway point between the two. The addition of a little bit of Lillet is brilliant.
