Another excellent cocktail tried a few times now. This last iteration I increased the Yellow Chartreuse to 7.5 ml which for me improved the balance between the Crème de Violette and the other ingredients. I suspect though that this in part is because I may not be using the best of CdV. I would love to try this with Benoit Serres Liqueur de Violette if I ever manage to source it in Canada!
