With plenty of ice in an old-fashioned glass, add the ingredients (Mirabeau pink gin, Lillet Rosé, and Campari). Let the ice work its magic by giving it a gentle stir to start it melting and diluting the cocktail to your preferred taste.
Take a long peel of orange zest (avoid the pith) and wipe it around the rim of the glass. Pinch the peel over the drink to express a little oil.
