I researched this a bit and discovered the original recipe calls for *sweet* oloroso or PX sherry. My understanding is that in the EU, “sweet oloroso”
is known as “oloroso dulce”.
This would considerably change the flavor profile of the drink.
Original Chris Hannah spec with OFTD rum, John Taylor falernum, Averna, green chartreuse, Ango orange bitters, Peychaud’s bitters. Wow. Really delicious, complex and layered flavors. A bit sweet? Perhaps, but I think it needs the sweetness to tame the heat from the OFTD and chartreuse. Not for the faint of heart, as it is quite punchy. But flavor for days. Highly recommended.
