Nice. I like it. Campari and gin versus Grand Marnier is a nice balance. People might want a tad more acidity. I can't get my orange peels to look right, so maybe that is it but next time I might add a dash or two of lemon juice (or lime?) to brighten it up.
History? I wonder where this cocktail came from? Usually you can find something online, but not this one. Every recipe I came across was copied verbatim (and honestly all of the sites seemed like click-bait) without any comments or notes.
