Your choice of genever and orange curaƧao greatly effects the balance of this cocktail. Salvatore uses Rutte Old Simon which is not only a fantastic genever...
I just made one and watching the video after, looks like he strains this into a coupe with a block of ice. I'm not sure the drink requires it but who am I to question Salvatore?
I'm not a fan of chunks of ice in a coupe. For me best either served on-the-rocks or straight-up. Hence, I took the liberty of tweaking Salvatore's serve.
