Black Forest Sour

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

Chill an Old Fashioned glass to prepare it for serving.

Craft a garnish by twisting a strip of lemon zest, setting it aside for later use.

Combine Jägermeister or another German amaro, cherry liqueur, pineapple juice, freshly squeezed lemon juice, rich sugar syrup, and your choice of egg white, Vegg White, or Fee Foam in a shaker with ice. Shake thoroughly.

Strain the mixture back into the shaker, discarding the ice.

Dry shake the mixture without ice to achieve a frothy texture, then fine strain into the pre-chilled Old Fashioned glass.

Express the lemon zest twist over the cocktail, releasing its aromatic oils, and use it as a garnish.
