Tried this one (twice!) with different Calvados and Blue Curacao as I ran out of Orange. Besides the fact that the final color now looks as if this drink was made in Tchernobyl, this really IS a revelation.

Choice of Calvados however made a huge difference. I tried one with a Boulard Calvados VSOP, which makes for a more full bodied but less 'sweet apple'-taste, whereas a 'simple' 2 yr casked Calvados gave this cocktail a lighter, fresher taste.
Both were however very pleasant!
