Negroni Frappé

Select and pre-chill a highball glass.

Prepare a garnish by grating fresh orange zest.

Shake the gin, amaro, rosso vermouth, freshly squeezed orange juice, and orange bitters with ice until chilled.

Strain the mixture into the pre-chilled highball glass filled with crushed ice.

Churn gently to redistribute the ice, adding more crushed ice if needed to fill the glass.

Finish by grating orange zest over the cocktail for a fragrant garnish.
