Pairs unbelievably well with a Terry's chocolate orange. Substituted the expressed fresh orange for charred dehydrated orange which also works well. I wonder if the previous poster suggesting notes of cocoa (dash of chocolate bitters?) might be onto something.
Ever so slightly too sweet - read the comments before making. Would dial back the agave a touch to accommodate Fee Aztec bitters but otherwise a delicious sipper. A few grains of salt also lifted the flavour somewhat.
I agree with Avery, definitely not a wow drink. Not unpleasant but “shallow” is a good description. I had even used a spiced simple syrup to complement the rum flavours yet somehow it's very unremarkable.
