Tanner's Amaretto Sour

Use 2:1 rich simple syrup for its listed portion.

Chill a cocktail coupe glass in preparation for serving.

Prepare an orange zest twist as a garnish.

Combine Adriatico Amaretto Liqueur, straight rye whiskey, freshly squeezed orange juice, freshly squeezed lemon juice, rich sugar syrup, Fernet Branca liqueur, and either egg white or cocktail foamer in a shaker with ice.

Shake vigorously and strain the mixture back into the shaker.

Dry shake the cocktail without ice to achieve a frothy texture.

Fine strain the cocktail into the pre-chilled coupe glass.

Express the orange zest twist over the drink, then use it as a garnish.
