Like many others I had to make substitutions, in my case 2 dashes of smoked cinnamon bitters in place of the syrup. I rather like this drink. I'm not sure I get any rosemary, but the cognac/PeM/Heering combo is really quite pleasant. The Scotch adds some interesting light smoke and an additional dimension to balance the roundness of the cognac. Overall quite nice, one I would gladly make again.
