Perfect, even without egg, as has been suggested.I used a muscat grape pisco from Chile.

Delish! Very moreish (I had to have one more immediately).
Low alcohol too (less than 1 standard drink according to the above).
I had some fresh, tart Granny Smith apple juice, which kept sweetness down (alternatively add a few drops of lemon juice, I reckon).
A wonderful cocktail. 5 stars from me.

An unusual combo of flavours that I like. I'd go one notch lower on the Campari.

Lovely! As mentioned in the text, there's a lovely hint of plum in this well-balanced drink. 5 ingredients, but widely available -- easy to make.
