A brandy-forward, cherry and herbal-flavoured late-night sipper. If you're in the mood for an on-the-rocks serve, then try 40ml cognac/brandy, 40ml Guignolet...
I had to use Cherry Heering, and I adjusted by adding slightly less (a scant ounce) than the recipe called for, as I read it was a bit sweeter. It still came through bit too heavy, but I think maybe going to 3/4 might be better. I was also thinking of maybe cutting in just a little Luxardo, but that is starting to get closer to a different cocktail.
