Delicious.

I subbed Rye for bourbon and Woodford barrel aged aromatic bitters because that’s what I had.

This was my impression as well. I prefer bitter leaning cocktails and I found myself enjoying it more as it diluted a bit from the ice melting.

I don't currently have Sfumato at home. I do have dell'Etna and Cynar. How much of a difference would it make to use either of those amaros and which would you recommend? Second question, how much am I missing out in general by not having Sfumato?
