Dans Le Jardin (In The Garden)

Use 2:1 rich simple syrup for its listed portion.

Select and pre-chill an Old Fashioned glass.

Prepare a rosemary sprig for garnish.

Shake the gentian liqueur, Hayman's London Dry Gin, freshly squeezed lemon juice, rich sugar syrup, and egg white (or Fee Brothers Fee Foam) with ice until well chilled. If using, add Chartreuse Élixir Végétal.

Strain the mixture back into the shaker.

Dry shake the mixture without ice to create a frothy texture.

Fine strain into the pre-chilled Old Fashioned glass filled with fresh ice.

Garnish with the prepared rosemary sprig.
