The Laverstoke

Squeeze two freshly cut lime wedges into a clean glass and then drop them in. Measure and pour in the elderflower cordial, Martini Bianco and Bombay Sapphire gin into the glass over the lime. Swirl well to mix. Fill the glass completely full of cubed ice and briefly stir to chill. Finally, pour the ginger ale down a twisted bar spoon (into the spoon end) over the ice and gently stir the cocktail at the same time and fold to combine the liquids. Garnish with a sliver of freshly mandolined ginger and a large gently slapped mint sprig all grouped together on one side of the glass, and serve.
