Serpentine is a refreshing cocktail made with Gin, Melon Flavored Liqueur, Fresh Lime Juice, and Pineapple Juice. The drink is said to have originated in the Caribbean and was popularized by British sailors who brought it back to England. The first recorded recipe for Serpentine appeared in 1878 in a book called ""The Bartender's Guide"" by Jerry Thomas. The guide recommends serving the drink in a tall glass with cracked ice and garnishing it with a slice of lemon. Serpentine is a flavorful cocktail that is perfect for summertime sipping. Cheers!
