I decided to try this since my bottle of Sibilla hasn't been touched in over a year (it's intense!) and I really like grapefruit juice with other amari such as Cynar. I did make the following substitutions: Luxardo Maraschino as that is what I have, honey syrup instead of simple since it was made, and a pinch of kosher salt instead of making a solution. My grapefruit was pink, but I'd like to try white when I can find one.

Thoughts: for me, better on the rocks- the extra dilution and chilling softened the bitter and sweet notes. The maraschino was just a bit too dominant. I haven't had Maraska's brand in a couple years but I remember it being mellower. I'm tempted to play with adding a touch of something like Maurin Quina or Gran Classico next time, and maybe a little more lime, but overall this is good.

This was great. Close enough to a negroni to be delicious, but different enough to be a surprise.

Agree with Jaba above. The riff is there, but it’s not a copy. Bracing, more assertive. Delicious.

I like an ounce of vodka in there too, punches it up nicely.
