Notes
If you don't have D'Ell Etna, I might try Lucano, Abano or another Amaro that isn't so heavy on the orange flavors.
History
I found the Italian Conquistador a bit too sweet and orangey for my taste, so modified for more complexity and less sweetness.
Had only Angostura 7 y.o. and Amaro Lazzaroni - too dry for me, leans toward Fernet bitterness. Increasing sweet part next time.
