Amaretto Stone Sour

Chill a martini glass to ensure optimal temperature for serving. Prepare a twist of orange zest for garnish, setting it aside for later use. Combine the Adriatico Amaretto Liqueur, freshly squeezed lemon juice, freshly squeezed orange juice, egg white, Angostura Aromatic Bitters, and saline solution in a cocktail shaker. Add the lemon peel to the shaker and perform a regal shake with ice to blend the flavors thoroughly. Strain the mixture back into the shaker, discarding the ice. Dry shake vigorously to emulsify the ingredients and create a velvety texture. Fine strain the cocktail into the pre-chilled martini glass. Express the oils of the orange zest over the surface of the cocktail and float the zest as a garnish.
