In a cocktail shaker, muddle the pear with the honey syrup or simple syrup. Add the gin and a few cubes of ice. Shake until the outside of the cocktail shaker is frosty. Strain into a cocktail glass. Top with a splash of dry wine or sparkling water. Slap a sprig of rosemary to release the oils. Garnish the cocktail with the rosemary. Serve.
