The Prince Louis Cocktail is a refreshing and elegant drink that combines the flavors of gin, lemon juice, and elderflower liqueur. This cocktail is perfect for special occasions or a relaxing evening at home. The combination of the floral notes from the elderflower liqueur and the citrusy tang of the lemon juice creates a well-balanced and delightful drink. Serve it chilled in a martini glass and garnish with a lemon twist for an extra touch of sophistication.
