Mastiha Sour

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

Select and pre-chill an Old Fashioned glass.

Prepare a garnish by twisting a zest of lemon or orange.

Shake the Mastiha liqueur, freshly squeezed lemon juice, rich sugar syrup, and egg white (or your choice of vegan alternative or cocktail foamer) with ice.

Strain the mixture back into the shaker.

Dry shake the mixture (without ice) to achieve a creamy emulsification.

Fine strain the cocktail into the pre-chilled Old Fashioned glass filled with fresh ice.

Express the citrus zest over the cocktail to release its oils and place it as a garnish on the rim.
