I made this according to Grassi's original recipe and first accidentally forgot the Campari. Without the Campari I was really impressed by it as a night cap. It tasted a bit like a grown up cola without carbonation, which the lemon peel certainly helped to elevate. With Campari I felt the Ferro China kind of took the upper hand which it hadn't before. Next time I'll make it according to Grassi but without the Campari.
We have few of the ingredients for this cocktail. Undeterred, we substituted Barolo Chinato Cocchi for the Baliva, Noilly Prat as the dry vermouth, Carpano Antica for the Rubino and Campari for the Strucchi. We loved it.
