This is fruity and sparkling one. I love it by adding 7.5 ml of fresh lime juice.
In another version, kindly try substituting Creme de Framboise with Heering Cherry Liqueur: a natural winner.
There's a theory that the cloying original spec from Famous New Orleans Drinks (1937) contains a significant missprint. Instead of a full measure of syrup or "Hembarig", local bars actually used "himbeer essig", i.e. raspberry shrub. In any case, this version works because of the tonic, and I used the St George Crème de Framboise, which isn't overly sweet.
