Select and pre-chill an Old Fashioned glass.

Prepare a garnish of lemon zest twist.

Shake the cognac, Italian red bitter liqueur, freshly squeezed pink grapefruit juice, freshly squeezed lemon juice, and saline solution with ice.

Strain the mixture into the ice-filled Old Fashioned glass.

Express the lemon zest twist over the cocktail and use it as a garnish.
