Since I prefer my drinks on the tart side, I tried this both ways - omitting the sugar syrup and omitting the Grenadine. I liked the Grenadine only version.
Very tasty! As usual, I had to cut the Giffard Grenadine syrup quantum by half, so, 2,5 ml. I can’t really understand the widespread faiblesse for that particular candy/caramel taste that so easily takes over the whole cocktail experience.
